I made a strategy game where you play the US or China through the AI race, 2026 to 2030, sixteen quarterly turns in the browser. One run takes about half an hour. At the start, the game seals two dice you never get to see. Inside: how hard alignment really is, and how fast takeoff compounds. You get eval reports, but only as ranges, and they flatter you most exactly when your systems are least aligned. At the end you get a debrief which shows what your evals said each quarter and also what was actually true. I lost every run I played myself so far. Every number in the game is source-backed or a labeled design choice. Some of them are wrong somewhere. There is an issue template for challenging a number with a better source, and the better source wins. No accounts, no tracking, no server, works offline after first load. AGPL, nonprofit. Cards and parameters are plain JSON. Contribution is possible without writing code. Would like to have your thoughts if it is fun to play, how you lik

On this page there are two complete recreations of the original Gameboy Tetris game based on the commented assembly code. On the top level there is a C version that compiles to WASM but on every pixel of that version there is a GLSL shader also implementing the complete original code with a AI player making virtual inputs! Everything was planned by me and coded by Claude Fable. Brazilian tileset generated by Gemini so I'm not technically using any copyrighted assets.
