COME BAAAAACK
It's a little frustrating that I can't move horizontally while holding down the jump button. But I love that I can headbutt the face off-screen by jumping into it. And that I can pin it to the floor by jumping up and landing on top of it.
The hole in the ground is so narrow that it's hard for the player to fall through it. But you can spike the face down into it with a jump. Take that, face.
