Paroxysm is a short platformer demo which is lacking a full screen mode, though the author had promised this feature when the complete game is released.
Prince of Persia minus the angst equals fun. Slightly frustrating at times but the difficulty can be adjusted to your liking. Tutorial works well enough and doesn't require the player to spend half and hour learning all the controls.
