I love the idea and the art itself. My issue is the same as stated by Punica, especially for it being too slippery. Although, that doesn't bother me much. However, I'm not sure if it's only me or the screen is a bit too close, I didn't know the enemy is near and coming towards us. About the enemy, they move a bit too fast for me, since we have to control both of the characters, I had to repeatedly smash the Q button (lol) in order to save both of my characters. Perhaps lowering the enemy's speed might help or take the camera a bit further away from the characters would do the trick. Despite all that, great job!
