Thanks for the feedback!
I'll be experimenting a bit with changing the jump gravity/air control once I can update it. as for the spawns, seems to have a bug on the skeletons (on the first castle room) where if they spawn on a corner they will clip up without the little raising up animations, all enemies besides the skellys are spawned in fixed locations when the game starts. the delay on the different shots was designed intended since each one has it's own damage value, game would be unbalanced if you could, for an example, spam the grenade one without a wait time.
