Hey, I gave this a try.
Overall everything seemed to work as expected. One big thing would be to add a "run" option by holding shift.
One question, I wasn't sure what the "Press e to learn to jump" thing was.
Here are a few other thoughts for additions
--Add UI for parameter sliding: Player speed, jump height, things like that.
--For the car driving controller, would it make sense to let the person still look around with mouse, even if the car is going a different direction?
--You could get really out there with abilities and modules, like double jump, grappling hook, jet pack, wall running/parkour
