About the game
Unifrost is a 3D platformer that looks like a pen drawing: white clouds and pale sky outlined in brown, with columns, brick walls and tiny hanging platforms scattered across the sky. You are a unicorn, and your job is to find the seven lost shards of the Bifrost, the rainbow bridge, which have been scattered across the clouds. The land is full of small characters who talk to you in speech bubbles and springy balloons that bounce you up to the high places.
Movement is the part the author clearly cared about. You gallop on the ground and build up speed, jump and leap, and on some surfaces you can lodge yourself in a wall and fling yourself away from it. Every shard you collect gives you something new: with each one you can press Space again in the air to make a rainbow and slide along it, so a shard is both a goal and a tool that opens up places that were out of reach. When all seven are found the game ends with a victory message.
The mouse turns the camera and the keys move you, so it is a game for a keyboard and mouse rather than a phone. Falling off the clouds is easy and just sends you back, so it is safe to try the risky jumps.
Benjamin Larsson made Unifrost for js13kGames 2026, where the whole game, zipped, had to fit in 13 kilobytes. The sound effects are made with the ZzFX synthesiser. The author says no AI was involved in the design, art, audio or dialogue.
Playing it here
Click Play, then click inside the game so that it can capture the mouse; move the mouse to look around and use W, A, S and D to walk. Press Esc to release the mouse when you want to leave the game. Nothing is saved between visits.

A few things worth knowing
Look before you jump. The camera is on the mouse, so turn it toward where you want to land first.
Shards are tools. The more you collect, the more rainbows you can make before touching the ground, so a place you could not reach before may become possible.
Falling is cheap. There is little to lose, so test a long jump before looking for another way.
