Expanding Body Platformer
A Kirby style game where you collect the powers of the monsters that you absorb. Eat. But they turn into more of like a centipede body part. Where your body just continues to get bigger and bigger and bigger. You can switch Powers by switching whatever part of the body is the head. So for example, if you wanted flying powers, you'd have to switch to the flying segment of your body and then you get to use those powers. But your body just gets bigger and bigger and bigger. Think of a platformer but with snake style expanding body.
So a puzzle platformer. Snake style expanding body. You eat enemies on the map to gain their powers. But it has the consequence of expanding your body into an unwieldy mess.
