That one really WAS awesome.
MOAR!
How to level: Find a boss [level 2, maybe 4]. Kill it and run straight off a cliff ASAP. Even faster: Play Arcade Mode.
Adventure Mode was great. Arcade 1 was boring. from the two minutes of it I saw. I won't be seeing Arcade Mode 2, because this game does not autosave, even if you're level 10. :(
