Hi. I told you I needed some kind of external inspiration to making coasters. And I just so happen to find a level from a game turned into a 3D mesh. I experimented some and look what happened!
So, this is a Corkscrew coaster set under the water environment of Clanker's Cavern from the game Banjo Kazooie, reaching speeds of 93km/h.
