Cool concept! As others mentioned the collision boxes are a bit large, personally I normally make them small enough to cover the head and body and not worry about arms and feet, it makes the game a bit more playable and fun, especially for people new to the game. The movement speed is really lacking especially if you die at the last moment and have to do everything again, but the overall concept is nice. I think there might be more to the separation idea in the game because of the broken heart icon I saw but I couldn't get far enough to see if there was anything, but had me intrigued :D keep at it!
