The art is AMAZING, really like the story images, very impressive on such a short time
The music is AMAZING.
The gameplay is fun and creative.
Movement feels too fast movement when player does not have the ball, maybe tweak it a little bit
There is no feedback when slow mode is on which makes it hard to tell if I accidently set it off or on, consider adding a timer icon or something on the screen.
There is no feedback on submit button so I don't know if it worked or not when I clicked it. And can be clicked twice.
Consider adding a fullscreen button.
