August 10th 2021 (yes, a year later) :D

discovered game breaking bug, 5 cards could hard lock the game (2x trashcan, 3x machine), immediately breaking it. As result: 8 cards removed from the deck (2x trashcan, 3x machine, 3x cog), and replaced by 8 other cards expanding the number of those cards in the deck (2x portal, 2x grating, 2x key, 2x lockpick)

August 12th 2021

[lockpick] card changes it’s mechanic (opens all 3 instead of 2x)

August 18th 2021

game start: each player get 9 cards instead of 7 (prolongs the game, prevents winning outright in third round).

Created more unique closed door variants (34 cards instead of 18 x2)

Deck size stays the same (100 cards), but is more varied.


March 5th 2024
