@pushycat: You have to push the red button first, guide the flying guy into the handy little pocket of green, then maneuver the flying guy to the coins.
@ghj1: You need to stand on one button to let the safe fall 1 level. Then push it so it is above a button and then stand on that button. The safe will drop onto you, killing you.
@jerrykimasdf: What you need to do is hold down the button, shoot, and then get off of the button so that the safe can be pushed away. Do that 2 times more except on the last shot don't get off the button. You can then hop happily to the spikes. Hope it helps!
Also, you know what would make this game a 6/5 instead of a 5/5? Online multiplayer. You could customize your runner, race with friends, and most of all, see who can run longest.
Awesome game. I can't make it past Level 1, but, hey, it's supposed to be REALLY REALLY HARD. So don't rate it down cause it's "too hard!!!!1!!!11!!!eleven!!!!!!one!!one!"
