This game is quite fun, although as people have said, it feels like an early version. When you collide with an object, there the purple light you play as slowly fades over a few seconds then goes to the main screen. This then means that as a player you don't really feel the collisions as much as would be good. You could think about changing that, and also think about changing the purple dot you play as a bit. It may look better as a square shape rather than a round shape.
