if you've never played iamp, it's a projectile based game where you dash to dodge the projectiles. you can dash in any direction, so the strategy comes in trying to time your shots to create an opening . It's very difficult to even land a single hit on skilled players. the fact that these guys are doing combos back and forth on each other is very impressive.
another fan made fighting game. basically a hybrid of MVC2 and GGX. They introduce a few new concepts like doing slams at the end of air combos and bouncing the victim off the ground to continue said combo.
