Changes: Audio: sounds occasionally continued playing after quitting to main menu. Visuals: ocean waves, camera shake, chat bubbles, resource overlays leaked across co-op sessions. Network/chunks: lag from chunk load/unload thrash when players far apart; mid-session save load didn't disconnect old clients. Player state: clients spawned dead/respawning after rejoin; wrong spawn positions; paused state leaked. Entity state: flora/creatures mismatched between host and client after starting a new co-op game; "under attack" bubble fired on save load with no enemies.
- Patch ver 2.0.5 - 22 June 2026

- Patch ver 2.0.4 - 21 June 2026
Changes: Fixed a bug where hovering over buildings would stop showing status tooltips, requiring a full game restart to fix Smoothed out creature movement so animals no longer appear to teleport or jitter around the map Removed a misplaced "YOU (HOST)" label that was appearing above the player character in single-player mode Fixed a crash that occurred when loading a co-op save and then backing out of the lobby to the main menu
- Patch ver 2.0.3 - 19 June 2026
Summary: Overhauled co-op networking with a hybrid peer-to-peer system that connects players directly whenever possible and falls back to a relay only when firewalls block it. Changes: Co-op connections now try to connect players directly to each other first, only using a relay server as backup when direct connection isn't possible Players behind difficult network setups (like apartment buildings or campus networks) can now connect and stay connected more reliably The host's plants and creatures now appear correctly on joining players' screens Lobby player lists and chat messages no longer go missing when joining a session Saving during co-op matches is now restricted to the host only, preventing confusion about whose save is authoritative Optimizing breeding pit structure Save failures now properly surfaced, and an overwrite data-loss bug fixed
- Patch ver 2.0.2: Co-op now runs direct between players. - 19 June 2026
Summary: Co-op no longer routes gameplay through the hosted server. Players connect directly: same-WiFi is instant over the local network, and players across the internet go peer-to-peer with the server only handling lobby matchmaking. Loading a co-op save now takes the host to the lobby first with each player's slot reserved, Start locked until everyone is back, and the saved world restores structures and placement correctly. A handful of performance and polish fixes round it out: large-base production is faster, lobby visuals are smoother, the pause tag no longer flickers on remote players, and the window reliably reopens on its last monitor. Changes: Direct connection between players — server now only handles the lobby and matchmaking; all gameplay runs peer-to-peer with no server in the middle. Same-WiFi players connect instantly over the local network, no internet needed. Loading a…
- Patch Ver 2.0.1: Performance Fixes - 18 June 2026
Summary: Fixed several internal systems were quietly accumulating leftover data from dead creatures, particles, and explored flora for the entire session, never cleaning up until a full restart. All three leak sources have now been patched, so frame rates should remain stable indefinitely during long sessions. This update is purely under-the-hood — no gameplay, balance, save files, or co-op behavior has changed. Changes: Decorative visual effects (thread tethers behind creatures, lurker fade, frenzy clouds and trails) kept stale records for creatures that had died long ago. Over thousands of spawns and deaths, this clutter built up until it choked the frame rate. Now automatically cleaned up every frame. Combat performance hardened. Particle effects (blood splatter, explosions, clouds) now have a safety cap so sustained combat can't overwhelm the system. Under normal play nothing change…

- Patch ver 1.0.19: Fixed game not being able to start from steam on some PCs - 9 June 2026
Summary: The fix adds a safety net that re-requests Steam stats on the first game frame if the initial request during startup failed silently on some PCs (slow Steam startup, network lag, debug timing issues), preventing achievements from being permanently blocked due to stats never loading.
- Patch ver 1.0.18: Parallel creature processing, frenzy cloud overhaul - 8 June 2026
Summary: This update introduces multi-threaded simulation dispatch, allowing independent subsystems and creature updates to run in parallel across worker threads with automatic core detection and graceful fallback on low-end hardware. Several player-reported bugs were fixed: ESC now properly closes build menus before pausing, audio no longer screeches during mass attacks, and Steam achievements unlock correctly again. The frenzy particle system was also reworked with per-organism staggered emission, reduced counts, and improved fade timings.Changes:Fixed ESC key not properly closing build menus before pausingFixed audio screeching when many entities attack simultaneouslyReworked frenzy particle system — per-organism staggered emission instead of global bursts, removed particle cap, reduced particle counts, and fixed fade timingsAdded multi-threaded simulation dispatch — independent subs…
- Patch ver 1.0.17: Demo-to-Full-Game Migration & Bugfix Patch - 7 June 2026
Summary: Fixes three player-reported issues: demo save achievements not carrying over to the full game, players dying during the evolution transformation cutscene, and deleted save files reappearing due to incomplete cloud sync removal. Changes: Achievements earned in demo saves now unlock correctly when loaded in the full game Player is invulnerable during evolution cutscene to prevent a broken death state Deleting a save file now properly removes associated cloud copies Steam cloud sync no longer loads saves when cloud is disabled by the user
- Patch ver 1.0.16: Achievements not unlocking for players upgrading from demo - 5 June 2026
Summary: When a demo player bought the full game and loaded their save, stat-based achievements would never unlock because the resync happened before Steam stats were loaded. Changes: Stats-based achievement resync now retries automatically once Steam is ready Previously unlocked achievements are re-pushed to Steam when the retry completes
- Patch ver 1.0.15: Mycelial Roots Rendering Performance Overhaul - 4 June 2026
Summary: The hyphal network that grows across the map is now drawn much more efficiently. Instead of sending each thread to the GPU one at a time, all threads of the same type are bundled together and drawn in a single pass. This eliminates hundreds of redundant operations per frame, especially noticeable in late-game networks with many active roots. Changes: All network threads are now drawn in a few grouped passes instead of one by one Branches, twigs, live threads, and fading threads each get their own batch No visible changes — the network looks and animates exactly the same Biggest gains appear in late-game networks with hundreds of active threads Reduces CPU overhead significantly during network rendering
