Beef and JW have a pretty good game here. Basically you play as this crippled telekinetic ninja master (the working title for the game was Crippled Master and the Deadly Trap Disaster) who can launch himself in one of the 4 diagonal directions once after every time he touches a non-metal surface.
It makes for some tricky spatial puzzles, but it never gets so difficult that you can't just get through a level by randomly trying different things.
It's even got a second mode where each level has a coin you must collect before continuing.
The game isn't lacking, but I think there's definitely more that can be done with the game mechanic, and it'd probably be fun to mess around with. Stuff like moving platforms and enemies and combining the psyclicking with one or two other types of motion could make for some interesting play.
Anyway give it a shot if you haven't already.
