The Character controller does the work for you indeed. And when I was teaming for a beginner Jam, I didn’t understood what it was so I couldn’t help. However you can totally use the Unity engine, and I already authorized something like probuilder. if it doesn’t do the work for you it’s fine (You need to learn by yourself first, it’s the goal of this Jam). Asset store is still forbidden. We are thinking about an “hardcore jam” for those that are not totally beginners but want to improve. If you already used the Character Controller, just say it clearly in the game description, you are here to improve not to be punished.
