i love puzzle games and i love the little bit of lore!
agree with the previous comment that there are some jam rules broken: subpixels and mouse input not turned off at the start (though i think it just goes in with any input, mouse or keyboard). imo, outside of the jam setting these aren't a big deal and they do not take away from the game too much.
a personal point, i use WASD since i have a 60% keyboard so the Q/E mapping is a little awkward. it's not a big deal since i don't need to swap/use tools too often in the current level but i can imagine it being annoying if i need to use tools often since i can't use both hands (i imagine Q/E with arrow keys is much less awkward).that said, you've all done a great job! the art is fantastic so i hope to see more of it with more levels as well :)
