About the game
Möbius Trip is a 3D race on a rainbow ribbon in the middle of a starry nowhere. The ribbon is a Möbius strip, the famous twisted loop that has only one side, so as you race around it the road turns over and what was the left edge becomes the right. The world swings around you, the colours smear into stripes and the unicorn, seen from behind, keeps galloping through it all.
You race against seven other unicorns for three laps. Before the start you choose how hard they try: Foal, Stallion or Alicorn. The track has rails on both sides, and scraping one at an angle costs speed, so the line through the twists matters. Crossing the middle line of the strip gives a short speed boost, and the rivals toot as they get theirs, so you can hear who is using it. A HUD shows the lap, the time and your place, for example 8th.
László Matuska made Möbius Trip for js13kGames 2026, where the whole game, zipped, had to fit in 13 kilobytes. The 3D track, the sprites and the sounds are all produced by code as you play, and the picture is drawn with WebGL.

A few things worth knowing
Cross the middle for a boost. Wiggle across the centre line of the strip and you get a short burst of speed, but only once in a while.
Stay off the rails. A scrape costs more speed than a clean turn, so ease into the twists.
Start with Foal. It is the easiest way to learn how the strip turns over.
