Thanks! Appreciate you taking the time to play our game.
Couldn't figure out the last level ! It was almost like I missed a glass block or something.
we've received some feedback now from a couple people around not being able to see what color the combined lights are generating and it seems like maybe this is what you were running into as well. the one glass block provided is enough to solve it; hint - the color difference for white light is super subtle compared to yellow.
ps - sorry about the Q key causing you to lose progress, this is great feedback. adding new input modes such as mouse is something I'll bring back to the team to see about ideating on post jam. (pps - I also had a branch of logic to improve save state data, but went with a really lightweight version for the jam release, so improving that might also help avoid progression loss)
