Arguably one of the greatest achievements of mankind: Creating a racing game using a children's coding website. This is truly beautiful.
EDIT: Oh, yeah, and if you think gameplay is slow, you can hold left or right on the top-down row levels, and up on most other levels excluding the tunnel to make you go faster and thus make the game a little more challenging. Just felt like saying this since the controls here can be confusing for first-timers lol
