Creative idea. Very good platformer.
The game is not perfect though. It is not revolutionary as far as the platformer goes. It has your typical stereotypical hub world, that is apparant in so many platformers. The game is very linear, there is not much to do on the side. It is also a very short game, which is a shame considering it is a very good game. The controls are a little messy. The music is not memorable, the the graphics are good, but not great.
Overall, if you like platformers, they don't get very much better than this. Mix that with the creativity of the game, and this is a very good game overall.
