Developed by Flippfly
for Windows, Linux, and Mac, Race the Sun
is a manic racing game about staying alive at insane speeds while soaring through infinite, procedurally-generated and player-created worlds.
You are a solar craft and the sun is your death timer. You will hurtle towards the sunset at breakneck speed in a futile race against time. You must delay the inevitable by catching energy boosts which reverse the setting sun - if only for a moment.
and a video are available for your viewing pleasure.
