Algodoo

Configurable random terrain made from polygons. It has 3 programmed terrain types - rough, bumpy but smooth, and huge rocks.
Always keep an eye on the yellow box or look ahead. it'll turn green when the smooth stage starts, and red when the rocks appear

Controls are the same as in the Wankel buggy scene - W is half throttle, shift+W is full throttle, S to brake, A/Z to shift. it has a centrifugal clutch for ease of use on the rocks part
