The player controls a solar-powered aircraft dashing at Ludicrous Speed through a sequence of landscapes containing various hazards. Inevitable failure, as is usually the case with endless-runners, is achieved either by a head-on collision with an obstacle, or by running out of speed after one's solar energy is depleted. See, since the vehicle is solar-powered, it's not only important to stay out of the shadows of oncoming obstacles, but as the game description points out, the setting sun serves as the game's timer, and the player has to extend the timer by racing the sun, collecting boost pickups to catch up with the setting sun.
The game also features a Level Editor, as well as an interesting feature where the main level is rotated every 24 hours, giving a different struggle for the top of the leaderboard each day.
You can play the Unity version here.
Race The Sun contains examples of:
- All There in the Manual: The Steam Trading Cards sort of give some story, although it's mostly detailing each of the obstacles and giving them names.
- Animal Motifs: Your vehicle very much resembles a bird, and birds occasionally drop items to pick up.
- Brutal Bonus Level: Apocalypse mode greatly increases the number of obstacles and the speed at which the sun sets, making it a true challenge just to get through one round.
- Deadly Walls: A somewhat downplayed example: while a head-on impact will destroy you, a glancing blow will merely slow you and reduce your Score Multiplier.
- Double Jump: One piece of equipment that you unlock for your ship lets you carry 2 jump powerups.
- Endless Running Game: Or rather, endless "darting forward maniacally-fast"...er.
- No Plot? No Problem!: Seems to be the theme here. You, your solar powered craft, and the ever setting sun. And the obstacle-like terrain...
- Lampshaded by the Battery powerup's flavor text. "We supposed this will help you do whatever it is you are trying to do."
- Portal Network: One of the unlocks allows travel by way of this to other player-created worlds. Another warps you to the end of region. Both warps resets the sun.
- Riding into the Sunset: Justified in that the player has to constantly do this to keep their solar energy up, and by proxy, their speed.
- Score Multiplier: One of the first unlocks as you begin playing is the multiplier meter — collecting 5 tris without collisions will increase the meter by 1.
- Super-Speed: Each session starts with a static shot of the level's beginning, and the player's craft dashes past at insane speed. And it just gets faster. Looking at is scientifically, chasing the sunset at the equatornote would clock your craft going about 1,400 mph (just under 1,700 kph).
- Theremin: The soundtrack occasionally uses this kind of effect, particularly when the sun is about to set.
