ok so some honest feedback, I know you've said you have updated it some on the main page but I will give my 2 cents,
1st no ambience / sounds hardly I would add some ambience or allow a player to play some music while working. as a janitor may do.
2nd, the action of picking up items and using seems a little jank to me, and can accidently cause a "mistake" if it doesn't get placed quite right. items should not land hard if not thrown.
3rd, rats can cause you to make "mistakes" I think only the player doing the action should be considered.
4th, the is related to items been picked up a bit jank, but if close enough to a wall items will go through the world and be gone forever.
5th, rats can kill there self way to easy, you could just wait for them to kill themselves while working.
6th, may been fixed already but the start a new game button does not work, and the player shouldn't be-able to move still after the fact.
The graphic's are decent. thats is all, depsite the flaws, I like your take on it.
