Great game! In terms of improvements, I feel that more levels would be good, and the last two levels seemed to have bugged out on me when I switched the light while on a surface, allowing me to walk on air. More clarity on what pieces I can or cannot walk on would be nice.
As for what I found awesome, the art direction is very nice! I like the subtle animations done on the subject. The sound effects, though a little on the louder side, were pleasant and fit the theme, like the music. The originality and theme are great. A great entry overall! :)
