Stab the rainbow is a high-speed WebXR runner built on A-Frame for js13kGames 2026, with all custom code strictly packed under the 13 kB zip limit (+ the allowed A-Frame library).

Crafted primarily for WebXR VR headsets, giving you the authentic feeling of being a galloping unicorn! You can play on desktop, but you will miss out on the magical sensation of physically being the unicorn—not to mention the glorious sight of a human in a headset aggressively headbutting space clouds and leaping over gaps on their living room rug.

Rainbows decay under cosmic entropy. Keep the 7-lane celestial highway intact beneath your hooves as paths lose energy and dissolve into the void. Stab oncoming color clouds with your crystal horn to recharge the track to 100%, rack up combos up to 8x, and stay on your feet before plunging into the abyss.

Controls: In room-scale VR, take physical side-steps across lanes, jump over gaps, and headbutt forward to strike clouds (controller grip and triggers work as a couch backup). On desktop, steer with the mouse and left-click to stab, safely sparing your ceiling fan.
