Hey, thanks for your feedback. I added the controls. For the second room, it’s as simple as that: Make every field green by walking on them. Reset using the Button in the wall. In case you meant room 1 (cause it starts at 0), it’s even simpler: Press the Button in the wall.

I have now given in another try and have updated my ratings. Overall I liked it. I am not sure if the last room qualifies as a puzzle, but it must've been something fun to program, so I give it a pass. The shadow labyrinth is also not a good idea in my opinion without sound cues when pressing you've pressed all the button. Other than that, I think that the difficulty curve is a bit all over, but since it's a jam, I get it. Great to see an Undertale inspired puzzle game!
