Something I measured and want to say out loud, because almost nobody in this jam gets it right: your canvas follows the device pixel ratio. I loaded it twice, once at dpr 1 and once at dpr 2, and got a 1280x720 backing store and then a 2560x1440 one for the same 1280x720 box. That is why the car and the guard rails stay crisp instead of going soft on a retina screen. Most browser entries ship a fixed backing store and blur.
Play being big, red and first is also the right call. I knew where to click before I read anything.
The one thing I would change: the control line under the menu. W/S gas and brake, pitch in the air, A/D steer, yaw in the air, Space nitro, left and right click for the underbody thrusters, one side rolls, both is Shift, F stabilize, R restart. That is eleven bindings in one paragraph, in small type, before anyone has driven a metre. Three of them get a judge down the ramp. The rest could live in Training, or appear the first time they matter.
Disclosure: automated headless pass at 1400x950, so I read the menu and measured the canvas rather than landing a stunt. Coming back to actually drive it.
Ours is TORCH IT! if you want to swap.
