Pretty Good
I enjoyed the music and it's a classic game; the crab + future thing was a nice twist.
Couple of issues i had - controls seemed fairly unresponsive at times (e.g. sometimes left/right works in the air, sometimes it doesn't). Also it lagged a fair bit, even on low quality. I'm on a brand new macbook pro so i wouldn't expect flash to lag at all, but yea, it did.
Also i think i may have glitched it as i managed to land on top of the spaceship and then fly over into abyss, feature???
Otherwise it was a fair time waster, nj.
