FAQ

Game builder questions

What can the AI game builder make?

Platformers, dungeon crawlers, racing, tower defense, cozy RPGs and simple 3D games with three.js. Each one is a single HTML file you can play in the browser.

Can I change the game after it’s built?

Yes. Ask for changes in the same chat ("make the jump higher", "add a boss") and KOTO edits the existing code.

Can I share my game?

Yes. Publish it and you get a link anyone can play, with a Remix button so friends can make their own version.

Is it free?

Free accounts get daily credits; a build costs a few credits.
