I managed to get myself stuck since my witch had fallen over dead to the buzzsaws in AI follow mode. They still had one heart and the game hadn't ended, though, so this might've been a bug. I'd suggest adding an auto-dodge to the AI follower otherwise the game turns into a babysitting escort quest.
Controls need a lot of improvement, neither character feels fun to control (Witch less so, since she takes forever to aim and does barely any damage). Another thing that could be snappier are enemy deaths, they stay on screen for another second or two before finally deciding they should keel over and disappear.
