Thank you! Yeah I had a loop in there at some point but it was too boring so I put in terrain generation lol (do some donuts and you have a loop!). I really wanted to put in webRTC multiplayer (I might after the jam), but I burned up too much time trying to keep the AI from driving into walls.
Thank you for the tip about the new game option tanking performance. That was there for the windows build, after the jam I'll pull that off the web build, starting a new game can just be refreshing the page.
