Summarise your game!
An idiot who has no fighting experience at all rushes into battle with a sentient sword. As the sentient sword, you have to defeat as many monsters as you can... while also making sure that the idiot wielding you doesn't die while he runs around making stupid decisions. You can switch between your shield form, sword form, and bow form. Slashing as a sword can take care of enemies close to you in a pinch. Shooting an arrow as a bow can take care of enemies that are further away. Bumping enemies back as a shield can protect the idiot wielder, as well as set you up nicely for a combo (defeating multiple enemies in a single slash or arrow awards bonus points!).

Please explain how your game fits the theme:
The person wielding the weapon cannot be controlled, he moves on his own. You are the weapon itself, forced to stay with your idiot wielder as he moves about.
