I'm with ya boss. Devil's Crush is good, but Alien Crush kicks it's ass methinks. The music alone is much better and there are fewer cheap aspects. There are too many angles in Devil's Crush where the ball is out of reach and falls through the flippers.
I have both, and I think Devil's Crush is easily superior. I mean it has all the boss challenges and a heck of alot more going about on-screen and interaction with the board. There's just more to do.
