Sick, man. Siiiiiiick.
When you were making this game, did you say to yourselves, "Hmm...once they've gotten to nearly maximum speed, how can we mess with their heads even more?" and then answer "Let's have mines that white out the screen!" OMG those things scared me the first time. And the second.
Anyway, this game is fun, addictive, challenging, and looks great. The only improvement I can think of is an on-screen timer of some sort for the invincibility...it's really frustrating to have it turn off when you're right in front of a pillar or whatever.
And to anyone who says the controls are sluggish: You really expect a wire cube to turn on a dime as those speeds?
But like I said, Great Game, 5/5, 10/10.
