Arrow keys to move, Z to change cars (Limo, Koenigsegg Agera R and McLaren P1), and X for handbrake. You are the governor of a small island with no rules. Drive around in your car of choice and go as fast as you want. Oh, and don't use fullscreen. It lags a lot. Or run on Phosphorus: http://phosphorus.github.io/#76050808 The roads are really low-def, though.
The Koenigsegg and McLaren are from @WO997; I just recolored them. Everything else is mine. Including the limo. The red Koenigsegg is a Need for Speed reference. v1.1b: Tweaked the limo's steering. No more limo-drifting :( v1.2: Added a limo, drawn completely by me. You can now see how cruddy my art skills are :P v1.1: Added a Koenigsegg Agera R as one of the car options. v1.0: Made the map more than 2x bigger. Yay! :D v0.1: Initial release.
