We're in the process of patching this out in an update, in addition to adding a button on the HUD to quit the minigame manually. Unfortunately, this is a fairly common problem. We're very sorry for the inconvenience, it sounds like you may need to restart your game in this case. Be sure to save often. Again, we're in the process of patching out the issue with enemies getting stuck in objects. Sorry for the trouble, and thank you for your interest in this project!
