  Some UI bug fixes and manual editing of keyboard controls in a text file are part of this quick patchKeyboard controls can be manually edited in the "controls.txt" file that gets created when running this version of the game for the first time and can be found in :\\Users\\ \\AppData\\Roaming\\OnlyOne\\Only One\\Documents (doing the in game UI for this will take some time to do for this and won't be available soon but for now you have some control over keyboard commands)Rightmouse button 'move to' can be turned off in the 'controls.txt' to revert back to stopping when letting go of the right mouse button for movementSmall deadzone has been added for mouse movement close to the characterFixed Trial target scores for 21 sentinels , 10 imperial soldiers and 8 red slimes adjustedFixed ui issue with daily sacrifice menu, character select, and hitting pause while selecting new powers when you…

• Only One 1.301 - 27 August 2026

  This is the first patch and fixes some minor issues and changes the right mouse button move to ‘go to click’ making it easier to move without having to hold the right mouse button instead of stopping when letting go. keyboard movement is still there but it's not advertised in the controls diagram. Gamepad and mouse movement gives the most fluid control for movement and is the best way to play the game, but I still want to keep keyboard controls for those who prefer it. I debated removing the ability to click the abilities with the mouse manually, but since some people will play with keyboard movement they may prefer to use the mouse to trigger the abilities instead of the keyboard.Right mouse button click moves to locationSimplified controls diagram (remove focus on arrow/wasd movement)Iron Bolt slightly easier and Tower Knight faster and more aggressiveUI changes to progress barShow ab…

• Only One is finally out! - 25 August 2026

  Fixing bugs till 10 am this morning and finally hitting the release button. It's been 8 months since I announced releasing Only One on Steam and it's finally out. Fixing old and new bugs, adding new enemies and 2 new bosses plus reworking existing abilities and spending way too long making sure the game supported controllers as well functioning on steamdeck. It's done.Please forgive me if the game still looks a bit dated, it's on an old engine that doesn't get much love and it's what I have to work with. If there are any issues please report them.If you are enjoying the game please leave a review. The more support this game gets from the community the more time I can put into it and yes there is still more that can be added. I still have achievements to do!Thank you all for the support and sticking around till release, I wish I could have gotten it to you soonerErnest

• Only One Steamdeck compatibility - 23 August 2026

  Only One runs great on steam deck! But make sure to run it via protonGo to the game properties on steamdeck and check the 'force the use of specific steam play compatibility tool' currently the default option works fine. Only One will still function without doing this but you will not get any music streaming and there is odd behaviour from the dpad, and on one occasion a user lost his save file.

• Only One out August 25th - 20 August 2026

  Only One is nearing it's release date August 25thI probably could have released a half ass version back in January but I wanted to improve the game in every apsect. The biggest thing getting full controller support for the UI and have it working on Steamdeck so the game could be played the way it's intended with a controller. Here's a small list:Full controller support for playstation and xbox controllers2 new mid level bosses, 2 new enemies (golden archer, sentinel)New hero - The Knight Pillar is more vibrant, some character art improvementsAI, attack timing, behaviour physics and behaviour of many characters changedMajor wave changes and addition of new enemiesNew TrialsEndless mode speeds up time and spawns by standing still on the faceCripple changed - attacks on non boss enemies slow movement and attack speed by 40% for 7 seconds Many minor tweaks and bug fixesThe game will release…

• Only One is coming to steam - 20 January 2026

  After many years of requests Only One is finally coming to steam!Only One on steam will be the full game, no in app purchases and no ads. The game will sell for less than $10 USD2 more enemies and at least one boss is being worked on for both the steam and mobile version. ChangesCurrently the game will have a lower grind than the mobile version (3x more power currency) and the additional characters can be bought with power but will unlock at specific levels.Controller SupportGame controller support is limited to combat only but because it does not currently support other parts of the interface in game it cannot be listed in Steam as supporting controllers. Adding controller support to the UI would take significant work but if there are significant wishlists, I will add it. That and even more content. So please spread the word and wishlist Only One, the more wishlists the more features a…
