This game is certainly fun, the music is fantastic (better than 2's?) and the level design is nothing short of genius (if you loved Portal, you'll love Galaxy Man's stage).

But the difficulty. Oh, Karzahni, the difficulty.

It's not just that the levels are hard. (They are.) It's not that the time trials are hard. (They are.)

The achievments are INSANITY.

Beat each boss in 10 seconds?

Don't take any damage in the whole game?

Don't kill any enemies?

Jump as little as possible?

Beat each boss with 1 pixel of health left?

Beat the game 3 times in one day, and once per day for 3 days?

Don't use E-tanks?

Don't fall into any pits?

Hoo, this game will keep me busy for quite a while. *plays*
