HexGL is a time-trial racing game in single player mode. The objective of the game is to finish the entire course as fast as you can.
Test out your mad driving skills (of course, without all the shifting) here. The game also includes speed boosts scattered across the entire course to increase your max speed for a short duration. Avoid bumping on the sides though, as it negates the entire speed boost and lowers your current speed. Continuous bumping also destroys your ship so you have to start all over again.
There is a special “GodMode: On” feature though, which completely makes your ship invulnerable. So if you just want to go on a joy ride, turn that setting on just before starting the game.
