Sprilo is a homebrew racing game that was created for the GitHub Game Off 2017 game jam. With nothing to race against other than time, you drive a car around a circuit as fast as you can. It was designed as a throwback to the old racing games made during the early 1980s when the technology wasn't advanced enough to incorporate more sophisticated features such as isometric views, cameras that follow the car, or third-person views.
