I will be changing how I post updates on Mushroom because I got a few complaints about too many changelogs 😅 (Sorry about that, daily updates should not equal to daily posts). Please refer to this post for any future 0.5.X updates.
Alpha 0.5.3 (July 9th, 2026):
Alpha 0.5.3 is here with more PDWGS improvements and fixes!
Additions
– Added PDWGS Structure Prioritization (Some Structures placed earlier than others) & Tile Locking (Once a structure is placed, then tiles are un-editable) to fix Cafeterias not guaranteed
Changes
– Changed how I debug the game & How Developer Mode works (I will NOT be going into detail)
– Cafeterias and Pod Rooms are now prioritized and locked
Fixes
– Fixed alertHibernator() fires when no Hibernator exists
– Fixed Alert icon shows when Hibernator is dead
– Fixed Eye alert directly manipulates Hibernator state without checking active
– Fixed Cafeterias not guaranteed
– Fixed Ensure Hallways Connected unbounded loop
– Fixed Inventory slot array length mismatch after respawn with backpack upgrades
Alpha 0.5.4 (July 11th, 2026):
Alpha 0.5.4 is here with mainly changes how Advanced Mode works. Unlocking is the same to prevent confusion. I also changed how a certain limit in Infinite Levels mode is bypassed, and one feature that was originally going to be in this update is postponed. (Yes, I know this is vague.)
Additions
– A new trigger is added, to unlock the certain limit
– Added 2 new secret achievements
– Added a toggle to toggling if players want to bypass the limit
Changes
– Separated unlocking Advanced Mode and bypassing a certain limit in Infinite Levels mode
– Advanced Mode now grants some usage of previously private Developer Tools (as cheats) and early in-development experimental features
Alpha 0.5.5 (July 14th, 2026):
Alpha 0.5.5 is here with a few QoL changes and improvements!
Additions
– Added new random posters that spawn in Building and industrial layouts
– Added a confirmation dialog when deleting a saved run
– Added “Copy to Clipboard” button in the error popup
Changes
– Save System (Beta) now restores darts on save load
– The Eye’s rotation is now paused while blinded
– Changed swap caption for better clarity
Fixes
– Fixed time tracked when opening certain overlays that pause the game
– Clear all data now properly clears all the data
– The achievement summary widget on the title screen now correctly updates and no longer requires a reload
Removals
– Removed the starting room posters because they break the fourth wall and doesn’t fit with the lore
Alpha 0.5.6 (July 14th, 2026):
Alpha 0.5.6, a part hotfix, part refactor update is here! I had to ship this update quickly because I became aware of an exploit. I will continue the refactor in 0.5.7, and whatever’s planned will be pushed.
Additions
– Added GameStateManager, which manages game states
– Added EntityManager, which manages entity states
– Added EnemyAI, which is a basic and generic AI for enemies (currently unused)
Changes

– Changed code to use entity states
– Refactored game code
– Refactored handleInput to use stateManager
Note: This update preserves save compatibility
Alpha 0.5.7 (July 15th, 2026):
Alpha 0.5.7 is here with the rest of the refactor and further exploit fixes!
Additions
– Added a Delete Save Confirmation popup in Save System (Beta)
Changes
– Custom mode scores will no longer be saved
– Moved Hard Mode, Single-Hibernator mode, Advanced mode into separate score pools
– Completely refactored the code, with several new files added

– Renamed some files

Fixes

Note: This update is compatible with older saves
Alpha 0.5.8 (July 16th, 2026):
Alpha 0.5.8 is here with a new enemy and couple of QoL improvements! You can now play Hide and Seek! Fun fact: I originally teased that back in January this year 🙂
Additions
-Added Teddy, he is a character, who wants to play hide and seek. If he sees you, he’ll will count to 5, before seeking you for 39.5 seconds. If you get touched, he’ll steal one item, or if no items, then 15 Scrip, or if no Scrip, then 5 health. If you have less than 5 health, then he’ll leave you with only 1 HP left. Countdown is displayed on the screen in big, red, bold letters. You can’t miss that one! Teddy also uses the files teddy.mp4 in assets\music\music\teddy\teddy.mp4, and teddy.png in assets\textures\characters\teddy\teddy.png. Fun fact: teddy.png was also created in January!

– Added a timer to Speedrun Mode
Changes
