Timing to slice is hard, but a lot of fun with two people! It is really fun to play tennis with bullets, wish the bullets got bigger as they got closer and that after each parry the speed increases for the bullets. Beside this add some better and more crazy fx when you hit the bullets, some clang on that, then that would be cool. Maybe even add a mechanic where perfect timing lets the players cut the bullets out of the air but it is like a one frame availability.
