Kind of shocked this is on the front page. It's got pleasant graphics, but the checkpoints are often too far from the really challenging stuff, the controls are lacking, that "ouch" noise is annoying, and worst of all, almost all my deaths were due to jumps across gaps exactly the same distance as your maximum jump distance or spikes/enemies that I couldn't see because they were on the next screen. The controls and sound may have been bad, but really the level design was the part that ruined it for me. If you want to design a platformer with screens, look at the level design of games like Metroid. Never force me to jump onto a platform across two different screens, or prepare for the movement pattern of an enemy I can't see because he's on the next screen. Those deaths aren't a challenge, they're cheap.
