Very creative!
If you plan to update this after the jam, i would love to see a sound rebalance so it is easier to hear the important sound of the enemy nearby, rather than it being half drawn-out by my walking/movement sound. Also i would love it if i could actually see a bit more, as the game is currently quite dark which makes mimics very difficult to spot when there are 2 empty tiles between you and the wall.
Other than these improvements, i like it a lot!
