Lags very bad, especially toward the end. The last few levels are painful not because of difficulty but because of progressively major lag!
that play more games' button got me killed a lot
YES!!! One damn thing: if you beat this one, you can definitely say that you achieved SOMETHING! When I first tried it I even thought that it is pretty impossible ;-) Probably the hardest skill - avoid game on Newgrounds with great background music. You think you are really hardcore? Try this!
Simple and gives lots of fun, but hard as hell in the end. But, you can feel "the spike" coming and it is not unfair, because you literally screw yourself.
