hello!! congratulations on submitting this game to the jam!!
polished, clean, and riddled with good puzzles! what a solid entry :) I do admit I had to check the hints on 2 of them, and I think that's a great addition to the game!
it seemed like the music settings weren't changeable when I returned to the menu after a game though? it seemed to only work at the very start of the game. I would've also liked to see it match the pixel style and not using the default Unity canvas graphics :)
other than that, excellent entry, kudos to you!! perhaps you'd like to give our game a try?
