Cool game mechanic and music.
Critique: I felt like I needed to have three hands for controls, because I was using the arrow keys. The guy was also very slippery in how he moved, making it quite difficult at times. I was also a bit confused on how the beam of the orb worked, sometimes feeling like it was pushing me when I was just using the left mouse button.
The cool: Fun level designs, for the ones I got to. I eventually got past "catch a riiiiiide", though I did accidentally fly off the top a few times. A decent border between difficult and interesting.
