Always love a little lights-out style game. The two things I enjoyed here that I’ve not seen in others (no idea if they’re common in the space or not), were the fact that lights could be on or off for a win state, and the lack of it being a full grid. This was enough to get my brain having to think a little differently about the puzzles which was refreshing.
I didn’t mind the music, as simple as it was, complex music might not feel right with simple mechanics. Also I know that music can be a huge challenge if you’re not a musician.
Felt like it didn’t really do anything along the vertical part of the jam. But perhaps later levels extend more in that direction, I didn’t make it far enough if that’s the case.
In any case, nice work. I am always curious with these sorts of games though. Did you hand-craft/validate the puzzles? or did you have some automated system in place for that?
