Hey just curious if i have a quick starter player controller system i use in projects can i use that as a starting point or do i have to start and build they system from scratch again for the jam?
Yes, you can include a controller system you made for previous projects, as long as you use it to create a new project. From the rules page: "You may also use your own pre-existing assets and code, but they must be used to create an entirely different game from the source material (not updating an existing game)."
