So I was playing the old version of A Koopa's Revenge II. The demo that was in the NG.mag alpha. And man, does it ever suck. The art style is lame, most of the art is traced, and the tweens are uneased and have only one joint per limb. Then there's the resolution problem, the blocks are so huge you can't see the ground when you jump. And the physics are terrible, the gravity is too slow, and it takes too long to run up to full speed aswell as slowing down again. I couldn't see it at the time, but it really blew.
What I'm trying to say is that I'm glad I started from scratch. The old Koopa 2 may actually be worse than the first. You guys won't be disappointed with this game. It was totally worth it to restart.
