I was toying with a DragonRuby game a while back, and did something like that. But DR also comes with recording reproducible playbacks, screenshotting etc. built in, couple hot reloading and easily being able to inject code into the running game, and it was great putting in place instructions so the agent could run the game fully and show off things for me in addition to allowing it to test things. I think we'll see more and more frameworks built to enable this - it's nice for human development, but it really pays off when you're working with an agent to have everything nicely runnable from a CLI and fully introspectible.

This is also what I've done for my multiplayer falling sand game: it's very much not vibe coded (too performance-sensitive), but coding agents can launch the game on my steamdeck and run benchmarks, take captures & verify rendering is bit-for-bit identical on a given machine, etc.

Agent can't _play_ the game yet, but that's on my list to experiment with.
