Extreme Tux Racer

Extreme Tux Racer is an open-source racing game with Tux, the Linux penguin, as the protagonist.

Controls are typical of racing simulators - the left and right keys change the direction of travel, but pressing the up arrow activates a specific function - Tux "rakes" with his flippers. Proper use of this command is necessary to optimize the path. Raking slows Thax down at high speeds and speeds up at low speeds. In the air, paddling can be used to increase the length of the jump. Raking flips Thax up on uneven terrain, and when you press and release the "energy" key (usually e) he bounces himself. Releasing the key during the jump lengthens it.
