I like puzzle games a lot, this one had challengin ones and thats a very positive point.
On the other hand, I had to experiment a lot to try to figure out what part of each map did, and what parts were hostile towards me or were just a platform with a strange texture. I think this was because of the lack of visual hints and different textures applied to the same concept of platform.
I think that with more polished textures this could be a very nice and challenging puzzle game. Maybe even a base for a sandbox game where players can create and share their own puzzles!
