About Keypress Express
A cozy idle game for Windows and macOS: a hand-drawn train runs along the bottom of your screen and moves forward as you type. You sell cargo, buy bigger engines and longer trains, and grow a railroad business. The game counts how many keys you press, not which keys. Developer Nitzan Wilnai says he wrote no code himself and that Claude Code built the game over 973 commits. It is free to play on Steam with optional purchases.

How it was built
Partially verifiedThe developer says he wrote zero code and acted as the idea, product and test owner. He says Claude Code wrote the code, the tests, an economy simulator and the Steam purchase integration over 973 commits, and automated most of the release process. Late in development it replaced the original Tauri renderer with winit, wgpu and egui because the old one did not work with the Steam overlay.
The developer described the idea and owned product and testing; Claude Code wrote the code. Written in Rust with data-oriented design.
