Way cool
It's simple enough to pick up and deep enough to not get boring too fast. The art is very well executed, too, although I think that finally dying feels a bit unspectacular.
I love the achievement Matrix because it instantly triggers the thing in our degenerate gamer brains that makes us punch the "play again" button.
The only game design flaw I see here is the boost mechanic and according powerups. It doesnt really seem very important, useful and well fit. But since you can absolutely ignore it it's not dragging the game down.
