I am going to re-make the entire course building system because of some collision issues, and to make it easier for the future me. It will be a spline-based system instead of a piece-based, so the player will have a lot more freedom. This will take a while, so don't be surprised if the next devlog is delayed. Also I am aware of the current physics bugs, so don't report them. Those should be mostly fixed with the new building system.
