Maybe there could be some kind of feature wheras inversions are possible only when launching off jumps, dunno how it would work, (maybe there's a button combination required and maybe it can be used for shortcutting purposes) but it would stop the problem of being stuck to the track and the oh-so boring loops.
I personally like the way the game's looking so far, looks like the technology of everything's starting to catch up with the AG technology;. i'm no graphics designer though so wha'do I know? :)
Weapons? Mines in a line, not sure about superweapons and i'd like to see the force wall make another appearance, it acted as a really good track obstruction and made you think harder and be a little more on edge while playing 2P.
