OK...
Concept is old but has a new system. What I DO NOT like is the collision detection. Numerous times I was still not touching the wall when I had to restart. Also, on the first level, I fell past the red circle and couldn't do anything else. Finally, the difficulty curve between Lvl 1 and Lvl 2 is insane. It would be better to fix the glitches and resubmit with potential new levels to learn the physics of the game better.
