Alright game. The pink background circles are good for demonstrating how powerful the void is getting. It isn't that great, and would make me kind of sick for looking at it for too long. The music is a bit irritating, and I think it's too difficult to last long enough. You might not have programmed enough items to spawn in, or made the void AI/algorithm too good at picking up the items that you want to grab, which makes you lose no matter what. There's no real tutorial, but the game is simple enough that it doesn't really need one. Simple controls and simple graphics.

Hmm, this was a rather simple concept, but those graphics and that performance sure were impressive! I liked the funky colors along with the pixel artstyle.
I'd suggest doing obvious things like expanding the game area, adding more boosts, characters, traps and so on and much more. Endless possibilities that could make this game even cooler ;)
