So we can't use even Unity's First/Third Person Controller? All should be coded from scratch?

Edit: it's in the rules that yes, we can use, sorry :(

"There are no restrictions on creation tools (Car/Character controllers, Unity store asset scripts ect). Game jams are the perfect setting to learn a ton of new things in a safe environment, so feel free to work with the tools you're comfortable with, some new feature you've been meaning to learn more about, or even a totally new game engine!"
