Concept of a pacifist platformer, since the gameplay is more about dodging enemies than fighting. Interesting ideas, like the difficulty which increases the closer you get to 100%. Indeed, the first playthrough quite trivial, if you are looking for a minimal completion, but quickly becomes very arduous for the secret ending. Interesting jump control, as it is possible to cancel and glide by pressing A in the air again. Unfortunately, the low diversity of gameplay loops and the sometimes cruel side of the title prevents this potential from blossoming: the subtlety of the movement system is spoiled by an uninteresting level design, so that the ideas are repeated after the fourth stage (of the seventeen available). Admittedly, the game is sometimes non-linear and offers secret rooms with particular gimmicks, but they are so cryptic that the average player will never learn about them. A pity.
