This Game Sucks.
I have to BUY new levels? Its a game you can finish in 10 minutes, not a game that you can play for bonus content like Fallout 3. Not to mention the obvious glitches like when jumping in the middle of 2 rocks diagonally you get stuck.
This game doesnt deserve this 0/5 and 1/10. it deserves a big -10/5 and -100/10.
