As far as platformers go, this is one of the better I've played. The jumping mechanism takes a bit of getting used to, but once you learn it the game becomes a lot easier. Also controls are fully customizable, so if they are not working for you, you can always swich them to a more comfortable setting. While some of the jumps can be frustrating, I've yet to face an obstacle that I felt was impossible. Besides, this is a platformer, the challenge is intended to derive from the environment, not the enemies.
The great news is the creator of this game is currently working on a remix of this game. This new addition will address the majority of the bugs mentioned, add more content, and improve on the current graphics.
