The game was fun! I just couldn't beat it in peaceful mode! These guys shoot very fast and im sure some people told you aswell, but at the same time i had fun with it at the first ending "The one where you kill enemies"! I would put more animations and feedback on shots, i believe that some changes in the jumping would make the game more enjoyable but that's my point of view hehe, even some death count would be awesome for the next update!
Great job m8 and keep your good game going :D
