The idea is really great, the controls are a little strange but for a jam a game with upgrades as you collect items is a big win already, just the dark was a little too much, there had one spider that give me a game over because i couldn't see it and it throw me down far from the head, and some times lumi gon into a wall and that made me lose a lot of light because i needed to wait lumi fall slowly down, but great game, had fun playing it, hope you plan to do more of it.
