I liked the concept of you being a spider that can walk on the floor and ceilings, but I believe the execution could be better. The levels were not really that challenging, as they clearly told you where to go, and there was not much problem solving from the player. I think if you made the levels more difficult themselves, or perhaps added another obstacle in the way that the player has to deal with to get to the next level, it would greatly increase the quality of your game.
