An endless runner that floats over your macOS desktop. Press Space in any app and the mascot jumps.
Best played while Claude is down or the API returns 529 overloaded_error. You were going to wait anyway.
git clone https://github.com/devsart95/claude-jumper.git
cd claude-jumper && ./scripts/build-app.sh && open "dist/Claude Jumper.app"Needs macOS 14+ and Xcode 16+. The first time, macOS asks for Accessibility so the game can see the space bar in other apps. It ignores every other key.
The jump is v = √(2gh) with g = 1,550 pt/s² and h = 125 pt, which gives 0.80 s of airtime at any frame rate. Obstacles top
out at 64 pt, so each one leaves at least 0.33 s to time the jump. The run speeds up for a full minute and obstacles are
placed by distance with that in mind, so even a last-moment jump lands at least 0.2 s before you have to jump the next one.
swift test checks all of it.
