You can do better.
Normally, I really like the FPA games, but this one really let me down. The buttons are extremely sticky, sometimes becoming unresponsive for 5 to 10 seconds. If I was holding a directional button when the keys stick, I keep running in that direction until the keys unstick, which is extraordinarily annoying. This problem made the normal FPA-type platforming extremely difficult... it took me probably 40 tries to get under 280 in the MicroTrial, not because I suck at it, but because at some point during the trial every time something would stick... my guy wouldn't jump when I pressed the button, he would start running one direction and wouldn't stop, etc.
Also, just now I made it into the level in which you have to swim through a passage to get to the next place, and I got stuck in the wall. My character looks as if he's falling, but I'm right at the water line, submerged up to what would be my chin. I cannot move or jump or even press the spacebar to pause the game, but I pressed "A" and he brought out a pencil, though that didn't do anything.
You really need to iron out the glitches; I hope your XBLA and PSN games have been more thoroughly tested.
Other than the glitches, the art is on par with previous FPA games, so there's nothing wrong with that, and the music was decent, although a little jarring when it looped.
