loved it, only things I'd suggest is to make it so that if you press up aiming up has priority over aiming to the side (that way you can run and throw your head upwards) and adding more mechanics (either level dependant ones or more character upgrades, or both, I personally like both haha)
I can see how this game could easily become a sort of story based game, a metroidvania, or both, and I could even see it having a fun multiplayer
maybe even having a stagebuilder or something when u got it all figured out
cant wait to see what u make of it haha
