Four riders. One mountain. No second thoughts. A low-poly, procedurally generated downhill racer. The author hasn't published an official live build yet, so this is an unofficial playtest we built ourselves from the open-source code. If you're the rights holder and have concerns, please reach us via the contact in the footer and we'll take it down immediately.
SUNBREAK (Downhill Club) is a low-poly downhill racer: four riders, one procedurally generated mountain, and a run that only ends when you crash or reach the bottom. The track is different every time, the art is flat-shaded and bright, and the whole thing is tuned for quick restarts.
The game is open source on GitHub (Imirushik/sunbreak-downhill-3D-game). The author has not published an official live build, so the version you play here is an unofficial playtest we compiled ourselves from the repository. If you are the author and would rather we did not host it, the footer contact reaches us and we will take it down immediately.
How to play SUNBREAK
- Steer with the left/right keys; the mountain pulls you downhill on its own.
- Carve wide around obstacles rather than braking — momentum is the whole game.
- Each of the four riders handles slightly differently. Try them all.
- The mountain regenerates on every run, so there is no track to memorise.

Why it's worth your time
The mirror is about 600 KB split across a hashed JavaScript bundle, a stylesheet and the page — the output of a standard Vite build. It runs at a steady frame rate on modest hardware because the terrain is generated as simple flat-shaded meshes rather than textured geometry. Keyboard only; there is no touch control in the current source.
Procedural terrain in a browser with a stable frame rate is the technical achievement here. It is built with a modern bundler (you can see the hashed asset files in the mirror), which makes it the most 'conventional' web build in the collection.
How it was made and where it lives
Source published on GitHub; the playable build here is compiled from that code. The author publishes as Imirushik. Original: https://github.com/Imirushik/sunbreak-downhill-3D-game. The Play button above runs our own unmodified copy, so the game keeps working here if that page goes down — which on free hosting usually has nothing to do with the author. Nothing about the game itself is changed, and the original stays linked from every page.
