Really neat and unique, novel concept. Minus-points for using assets from a real game/IP. But plus points for the "hero" adapting and improving after every single time that they "die". The game looks good, but since you took Link and assumably the boss (I am not fully 100% certain of that because at first I thought it is Vatii, but after looking it up nope, not Vatii), I'm sure the rest of the assets aren't made by you either
Also, there being only three moves you can do (technically four, but the fourth one plays into the volleyball-back-and-forth attack) takes away from the experience. You should be able to improve too, and gain other moves or even phases
Next time, do a game like this with your own assets and really flesh out the experience! This could have been so cool . . .
