AI Game Benchmarks
I hand coding models an old game of mine and a goal. They get one shot, no hints, no follow-up. Everything they build is scored by the same harness and playable below.
The benchmarks
See the brief each model received, then compare what the models built.
Voidbreaker
Turn the 2010 asteroid engine demo into a complete, addictive modern arcade game — not a faithful port. Use the original assets and feel as a springboard, then invent the systems that make players chase one more run.
Cruiser Reloaded
Turn the lost Phaser Retro Cruiser into a complete, addictive modern arcade game — not a faithful rebuild. Use the minified original and assets as a springboard, then invent the systems that make the run loop irresistible.
Retro Cruiser
Recreate a Phaser 2.0.7 arcade shooter as a modern web game. The original source is lost; the model gets only the minified deployed bundle plus the original assets to reverse-engineer behavior from.
Void Cruiser 3D
Combine Cruiser Reloaded's fuel, weapons, and drone combat with Voidbreaker's asteroid destruction and run progression in one complete 3D arcade game. Author the models and make depth matter in play.

Harness scores describe technical checks. They are useful for comparison, but they are not a final judgment of the game.
