I mostly like the game, especially the concept.
I found it too frustrating to try to play, though, because it seemed like the patterns were short and frequently the orbs appeared only moments before the comet crashed into them. I don't know if my mouse sensitivity isn't high enough to play this game or what, but I found myself annoyed at losing energy trying to figure out what was going to light up so that I could drag it. It would have been less of an issue if I didn't get the lose/defeat screen, and gameplay had just continued. I'm not entirely sure what the point of the energy was, though - it seemed like there was a finite pattern that you were trying to get through (I would progress to the next level even if my energy wasn't "full").
The sound was fantastic. I really liked that part of the game. I just found the quick reaction time and frequent setbacks to be too unfun to finish it. I think I got as far as level 3.
