The way you could switch between the characters was cool for me. I got into a bug/situation where one enemy trapped me on each side. They couldn't hurt me and I couldn't hurt me. But they kind of shielded me so that was nice.
Yeah the enemy behavior needs work, the colliders and hitboxes are a mess and you can easily get into these weird situations where someone is standing on somebody else's head and won't get off, or boxes a player in. Anyway, glad you liked the basic mechanic, and thanks for playing!
