Played about 20 hours so far.

Its not easy to pick it all up. The earlier stages are definately more fun, but space...man that is just crazy.

Feel pity for me, i payed $120. Special Edition though.

Depending on how you feel, you should probably wait for the price to drop down a bit.

The only online stuff I've noticed is that if you choose to link your account with that game, the stuff you make transfers between computers. Im on 64 kb/ps and its playing fine.

Each of the 5 stages is like an entirely new game, its quite good.
