The movement felt very rigid, you IMMEDIATELY stop i feel like a slight slide would be better, you spend to much time in the air maybe reduce jump or increase gravity. I fee like their should be more of an indication that you are low on health, because i died several times without knowing it a red border around the screen or something like that. Also make the fish more bouncy and make a section about it because the weapons are kind of rushed into your hands. Other than that a VERY cool game and fun!
