This is an incredible hidden gem. Very satisfying once you figure it out. Some more polish would be nice but yknow how it goes. My biggest complaint is the parry controls for keyboard are confusing since most games will treat arrow keys the same as wasd, and I didn't realize they were different and died like 10 times trying to figure out what it wanted me to do.
But after finishing it I just need MORE. I am selfishly requesting you make this into a full adventure platformer game with this frenetic kinetic traversal. Not sure you'd have to keep the player a bullet or w/e as a real character could accomplish the same thing while being able to have a story or something. The game is quite hard though, so adding some concessions for this like health would be good. Maybe even make it so bullets going the same direction as you don't harm you since you match velocity anyway. But man it is satisfying when you get the right bounce up a stream of bullets and they just pile up one after the other. Maybe you could play around with that and make the hit lag time shorter as it the parries stack to give to an even greater feeling of getting faster and faster. Idk, but I really hope something more comes from this. Very epic.
