I agree that its incredibly difficult to play, but I really like it. You have such a level of detail in the simple art, it's really cool. Neat concept - simple idea - REALLY frustrating controls!!
My biggest complaint is that nearly every direction key makes you go up or diagonal up, except for the down key. This makes it nearly impossible to properly align yourself to get orbs. If you went too far up, you're basically screwed - esp cause if you miss one orb you're basically screwed.
Anyway, really nice work!
Feel free to rip my control scheme apart!:
