- v1.1.11 Patch Notes - 18 July 2025
This update includes a fix for some memory leak issues. Other than that, this update mainly just involves internal engine changes. This should translate to a smoother and more stable experience for players.
- v1.1.9 Patch Notes - 22 June 2024
It hasn't been long since the last patch, but there were some critical issues introduced with v1.1.8. This fixes those issues so all is stable once again! Fixed bosses triggering as being defeated before they land Fixed Archer snipe shot crashing the game when it exits the room Fixed an issue that allowed striking Ancient Warrior after he was defeated
- v1.1.8 Patch Notes - 1 June 2024
Back again with another small patch. Fixed an issue with copied save files not remembering what items have been collected. Fixed an issue where changing Shin's costume while in-game did not consider if demonblade was unlocked. Improved controller glyphs and button prompts for Steam Deck and Xbox controllers. Most settings (audio, video, bindings, etc.) will now prefer local settings instead of Steam cloud sync. Players who use multiple devices often have different resolutions or controller setups depending on device, so it is more convenient if the game does not try to revert these every time they switch from one device to another. The video menu will now display the resolution of the current display when fullscreen is enabled.
- v1.1.7 - Fixed Projectiles - 6 December 2023
This is a quick patch for an issue that was introduced in the previous update. While trying to fix an issue with Mother's projectiles becoming invulnerable, a new bug was created which caused some projectiles to change speed or behave strangely. This update resolves that issue. Hopefully, all projectiles are behaving as they were intended from the start, now. ːHoppyHappyː
- v1.1.6 - Better Twitch Arena and more - 5 November 2023
This update has minimal impact to the core game, but there are a few bug fixes included. The focus instead is around the Twitch Arena, and providing a more customizable experience for the host. Arena updates Here are the updates related to the Twitch arena in this patch: Added option in Twitch Arena for a One Hit battle. This can be toggled on and off before starting the fight with a statue in the arena room. Enabling this allows you to fight as if the game difficulty was set to "One Hit", regardless of what difficulty your save file is. - You must complete the game at least once to unlock the One Hit difficulty before this option is available. Dying in the arena will now respawn the player in the same room. No more do you need to run all the way back to the arena. :D Individual spawn limits for each supported boss is now configurable in the twitch_config.ini file. Disconnecting from th…
- v1.1.5 - Menu improvements and polish - 16 August 2023
This update includes several bug fixes and quality-of-life improvements. Fixed Steam achievements and cloud saves not working on Mac. Added binding option for menu confirm and back. These are now separate from attack, jump, and roll. Changed file delete and "Restore to Defaults" buttons so they now display a confirmation window instead of needing to be held down. Fixed "Restore to defaults" resetting some unlock progress. Improved consistency for exiting in-game menus, like the map and scroll display. Escape now exits universally, in addition to the menu back button. Fixed an issue with the parry move consuming too much magic depending on the order in which buttons were pressed. It now consistently uses 1 magic bar. Added magic consumption indicator on the scroll for acquiring the parry move. Improved compatibility, localization, and visual prompts for certain controllers, such as Switc…
- v1.1.4 - Performance Optimization - 30 October 2022
This update brings some minor optimizations which should make Ato a smoother experience in general. Changes included: Button prompts for Joy-Con controllers added. Optimized map and lanterns so they no longer cause massive performance drops. Minor tweak which should reduce stuttering on some devices like the Steam Deck.
- v1.1.0 - Fix the things - 14 April 2022
This update isn't all too exciting, but fixes a few critical bugs. Fixed a crash when viewing credits from menu. Fixed an issue with Steam cloud saves and achievements not working on MacOS. The controller bindings screen will now display better button names depending on the controller you are using. Grass counter is now larger and scales correctly with resolution.
- v1.0.9 - The Grassy Update - 21 March 2022
Ato version 1.0.9 is out now. This update includes the following changes: Fixed a bug with warp gates. Grass has a long memory... It remembers when it has been cut. For all those speedrunners out there, v1.0.8 will continue to be available in case you want to utilize the warp glitch. (It is recommended to update unless you plan on running the "All Glitches" category.) To download 1.0.8, open the game properties and go to the Betas tab. Select "speedrun_1.0.8" branch. Please note: Loading a save file in an older version after it was opened in a newer version can cause loss of data. Use caution when switching between versions and only open new save files when running an older version.
- v1.0.8 Mac and Linux Release - 30 November 2021
Ato is now available on Linux* and MacOS! Both M1 and Intel CPUs are compatible on MacOS. It's the same game you know and love now more accessible than ever. This additional platform support means that it should be fairly optimized to run on Steam Deck as well, once it releases. We plan to apply for a Steam Deck verified rating (and test it on the hardware ourselves) as soon as possible, but it might be several months after Steam Deck releases due to Ato's relative obscurity in Steam's wide library of games. As a reminder, the Steam autumn sale is still going on. If you've been waiting for a Mac release to pick up Ato, now is a great time to get it while it's still on sale! ːJumpyCuteː *The game's engine (GameMaker Studio 2) only officially supports Ubuntu 18.04 and 20.04. (Steam itself only supports Ubuntu and SteamOS). That said, it should generally work on most Linux distributions, b…
- 1.0.7.1 Fixed display, demo updated - 9 October 2021
The last update introduced an issue with the window size for displays that don't have an ideal resolution. This patch fixes that. (Thanks to Octopoos from the Discord for reporting this bug and helping test the fix.) The demo has been updated to the latest version. The last time the demo was updated was 1.0.6.4, so this means the demo now gets all the bug fixes and optimizes that have happened since then. Credits have been updated to include individuals who helped with the previous localization update.
- v1.0.7 More languages available! - 8 October 2021
Language updates Ato is now more accessible than ever! Although the gameplay does not rely on any text, navigating menus is a lot easier if they are in a language you speak! This update adds multiple new language options including Arabic, Dutch, Danish, Polish, Swedish, Finnish, and more. In addition, the store page and achievements have all been localized to these languages, as well as most of the other languages which previously only had localized menu text. The remaining ones (Japanese, German, and Korean) will be fully localized in the near future. Some languages have also had their translations updated to be more accurate and natural than they were before. If you notice any issues, please let us know either through the Steam discussions or in our Discord. New players will be prompted to select a language the first time they launch the game, but you can always change your preferred…
- 1.0.6.9 Some tiles fixed, QoL updates - 30 January 2021
This patch fixes a critical issues with the tiles not displaying for one region of the game. It also includes a fun minor changes to polish up rough edges: Scrolls for abilities that use magic now display how many magic bars the ability requires. This is especially useful for Fatal Draw, as it's possible to obtain without having enough magic to use it right away. Some puzzles will now be automatically completed if you have already obtained the orb from that path. This reduces the pain of backtracking if you have to return to these areas because you missed a pickup or side-room the first time. Reduced noise from a few more sound effects when they overlap, for a softer auditory experience. Fixed an issue with enemies being able to trigger the combo achievement. Our last patch was a bit too loose with the grass dye; we've corrected the color of the grass on a specific encounter.
- v1.0.6.8 - Crash fixed; More Optimization - 27 January 2021
On the surface, this is a small update, but it could be pretty significant for some players! Fixed a memory leak which could cause crashes for some users after extended play sessions. Optimizations to reduce reliance on shaders. This can provide a fairly significant performance boost on devices which have integrated graphics or a weaker GPU. Fixed an issue with grass spawning inconsistently. (That is to say, it often didn't spawn!)
- Steam Cloud Saving - v1.06.4 - 26 September 2020
A small patch has been released that adds support for cloud saving via Steam. This will automatically sync save files between PCs as long as you are logged into the same Steam account and have the feature enabled. (It is enabled by default.) If you have existing saves, you must load up each file once in order for it to sync up. This update also includes a few bug fixes, including one for a crash under certain circumstances when using the throw spell. Enjoy!
- Demo Updated. Minor fixes - 16 August 2020
Since the last update, Ato has been updated to version 1.06.1 and now 1.06.2. These updates mainly just fix a few bugs in the 1.06 release, namely: Fixed issue with Boss Rush respawning you in the incorrect room under certain circumstances. Fixed issue that sometimes caused bosses to get stuck after spawning. (This was most prevalent with Leader and Twitch arena.) Fixed a crash when holding dash after a certain boss battle. Improved controller support/detection. You should now be able to switch between controllers seamlessly and no longer need to use the gamepad in slot 1. Fixed PlayStation controller button prompts displaying incorrectly. Added visual hints for a certain boss's spawn condition. Hopefully players will be less confused by this now when arriving at an empty room. In addition to these changes, the demo has been updated. It contains the same amount of gameplay as the old de…
- Boss Rush Mode and Optimization - 1.06 Patch Notes - 7 August 2020
New Mode: Boss Rush A new update has just dropped and along with it comes an exciting new mode: Boss Rush! This mode allows you to experience raw action as you fight through the bosses* back-to-back. Unlock condition: Achieve 100% completion and beat the game on any save file. In this mode, all of your abilities will be available from the start. You can choose any difficulty. You will start with max health, but you'll have to be careful because your health does not restore between fights! Challenge yourself to clear them all as quickly and with as few deaths as possible. *All bosses and arenas are included in this mode, with the exception of the following: 3 joke fights against Vagrant. (The final fight against him is included.) Child - This is more of a platforming challenge than an actual "fight." It didn't fit in with the frantic combat focus of Boss Rush, so it was left out. Optimiz…
- Twitch Arena Expanded & More Bug Fixes - 16 July 2020
Update 1.05 Fixes for a variety of bugs and adds a little extra polish. Here are a few of the included changes: Fixed a lot of sound effects not respecting the audio settings. Also reduced instances of overlapping sound effects to eliminate those ear-popping audio spikes! Fixed one spot where the player could get stuck while backtracking if they did not have certain abilities. Fixed inconsistent layering of certain objects in specific rooms. Chinese, Korean, and Japanese fonts now use their own font file. This makes loading them marginally faster in the language selection screen and takes less memory. Added a way for players to escape when trapped inside a wall of breakable blocks. In addition, this update brings some improvements for the Twitch arena! This feature is mainly intended for streamers, but don't worry - it is 100% optional and does not impact game completion or unlocks. Fam…
- Update 1.04 - 7 July 2020
This update includes minor fixes and visual improvements. Fixed an issue with orb progress not displaying correctly on file select screen. Fixed an issue that could cause the final boss to go out of bounds. Fixed timer display being hidden behind health UI. Improved FPS display. It is now small text in the corner of the screen so as to be less distracting. Runes that have been picked up will no longer display briefly upon entering a room before vanishing. Added save icon on map to a few rooms with saves that were missing it. Fixed charge attack visual effect showing even without the ability unlocked. Reduced noise caused by hitting multiple objects at once.
