Good
A nice platforming game, with challenging yet doable levels. The graphics and the music work well too, creating a quite relaxed atmosphere. This is a good thing, as some of the moves you are required to pull do need a fair bit of focus. The controls felt slightly frantic in the beginning, but they worked well once I got used to them. The only thing keeping this from a straight 10 stars, is a slight lack of originality. Platforming with the added possibility of flipping the map works well, but it doesn't feel that "fresh".
Overall a very good game, but the slight lack of originality kept me from getting drawn in completely. 9/10 and 5!
