Saw a facebook ad to give this a spin. I'm glad I did. I was a little skeptical that the "detached head" mechanic was going to be fun, but maybe just a revival of a mechanic found in medieval or Ratchet and Clank. So... I wasn't expecting something so surprisingly innovating! I love that the head is really the player and the body is more like a mechsuit i might temporarily use and abandon.
There is real potential here for the mechanics to build upon: juggling multiple bodies, different types of bodies with different or limited capabilities.
