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
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.
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.
