Fantastic, gameplay-wise, this might be my favorite out of the jam! I liked the lighting effects, esp still like background slightly illuminating, I think you could have a done a lot more of those without detracting from minimal (obvs time is always an issue). Echoing others, would have loved a %complete/ending at the end. I think I got it all.
I would have liked a minimap and controls explained but my only real issue was not realizing I could aim the bombs. In the upgrade room that required it, I thought you had to roll them off the ledge above and get really lucky, it was awful, but another person commented on it. Other than that, I really liked all the puzzles and interconnected-ness.
