This is an absolutely beautiful game, I love the style and artwork, the animations are fun and I can totally get behind the concept that this game is going for.
However, I genuinely think this game is not functional in its current state. When I first played, I was immediately flung out of bounds by the boss and had to restart the program. On my second try I basically ignored the fast forward and slow down mechanic and just stood on top of the bosses and mashed attack until they all died. I was also allowed to stand in the center of the record, which let me avoid all obstacles without worry.
I really love the concept for this game and the presentation made it easy to stick with the game to completion despite the issues but the gameplay really needed more time in the oven.
