VibeWare is a 100% vibe coded WarioWare style video game.

WarioWare is a popular Nintendo franchise that features a series of short 3-5 second challenges called "microgames". We figured codegen was far along enough to generate these kinds of mini-games, and we were right!

VibeWare has 2 parts: 1. Core game that that plays microgames. I don't know anything about JS game engines, so Cursor took the wheel. Total cost: ~$500 in Claude 4 Opus. 2. Micro-games generated by an AI agent writes, lints and validates the code. Total Cost: ~$5.50 to produce 10 reliable games (mostly GPT-4o tracked via AgentOps)

We submitted this as part of the "Game Changers Vibe Coding Hackathon" in SF and won!

One core learning was GPT-4o actually significantly outperformed Claude class models on code gen. Our suspicion was PhaserJS is better understood in the GPT world model.

It's fully open source, and you can even generate your own games: https://github.com/areibman/vibeware
