Awesome project!
I loved how you combined the gameplay mechanics with the story. The work literally becomes impossible as the days progress. It was a cool twist I didn't expect. I loved the addition of the dynamic soundtrack during the game's ending as well. The art style was super unique, and honestly, there isn't much I would change about this game.
One thing that I would add the next time you make a game in a similar art style is a draw shader to get into the hand-drawn look of the game. It would make everything come more alive.
Good luck during the jam!
