Really liked the mechanics once I understood the concept. As others mentioned, a tutorial would be helpful- didn't notice those light bulbs at the bottom but once I did it clicked a bit more. I think having the shadows on the floor (in the frog's space before the light is on) is a little unnecessary and led me astray at first.
Was sad to see it was only two levels! The puzzles were really cool and I could see that concept growing in some fascinating ways. You should be proud of the Prism block, that's an excellent mechanic for this game.
