Novaki publishes Strike Twice, an AI-built roguelite with documented model-judge tests

By GameSlash

Novaki's October 16 test reports a Claude Opus 5.5-built browser roguelite, its one-prompt experiment, self-including AI judges and distinct asset licensing.

Novaki published Strike Twice on October 16, 2026, a browser-based, top-down cartoon action roguelite featuring a matchstick character. The creator says Claude Opus 5.5 built the game through Claude Code from one common brief given to four competing AI coding agents.

Four agents, one identical brief

The project reports that Strike Twice received a 9.03/10 average and passed 100 hidden checks, taking five hours and 38 minutes before its run was stopped. Crucially, the blind reviewers were the four participating AI agents themselves, including an agent that scored its own game. These numbers are test-organizer results, not an independent human critic ranking or guarantee of game quality.

The developer explains that all four competitors received one prompt and the same asset-generation tools. Strike Twice's run generated 79 images, 25 voice clips and 25 music clips. A neutral 'Continue' was sent after a brief stop, but the team reports no human code changes or coaching. The estimated $154.35 is an API-equivalent price calculation, not an amount actually billed to a subscription account.

The code is MIT licensed while the game screenshots and media are CC BY 4.0 with Novaki attribution. This is one experiment's result; GameSlash has not independently run the hidden test suite or played the final game.
