Clever level design and a nice puzzle game. Could use a bit more tutorial getting into it. Also, there are levels were the rules about which lights cause you to shrink that are skewed. For example, in level 8, the lighting is the same color by the lightswitch as is in the hallway with the moving safe zones. But one damages you and the other doesn't. It feels a bit unfair to the player that way. But nicely done overall!
