About the game

You take a ski jumper from the top of the in-run all the way through the flight, and every jump's measured in meters.

Headwind and tailwind on the slope, and a choice of starting gates. Points for each jump, plus hill records to chase. Online leagues where every player picks a different jumper.

Press Space to start, then Up or Space to take off. Lean forward with Right and straighten up with Left. Land with Down for a telemark, or Space for a parallel landing.

It's inspired by SJ3, and every graphic is drawn in code on a canvas, down to the jumpers' faces. The music is by ssilk. Krischan described each feature, the AI built it on its own git branch, and Krischan "complained until it felt right". Most of the backlog came from friends who've played it since the beginning.

All the graphics are drawn in code on a canvas, the jumpers and their faces included. The only external assets are the music (by ssilk) and a few sounds. How I worked: I’d describe a feature, Claude Code built it in its own git branch, and I played it in a local preview and complained until it felt right. A lot of the feedback was screenshots with comments like “this layout is cluttered” or “why is he raising his arms in the portrait”. My friends have played it since the beginning, and most of the backlog came from them.
