/*3D Race Game by Little Cupcake I spent a lot time on this, so I hope you like it! Comment your best lap times!😄 3D track made in Creo Parametric. Future plans: - Better hit boxes - Add acceleration - Add more stages If you are using Android, open sololearn in Chrome browser with WebGL enabled. */ $(document).ready(function() { console.log=function(){};
