Gravity

Gravity is a 24-hour idle prototype. You are gravity: pull dust into a newborn universe, grow it into galaxy clusters, then collapse it in a Big Crunch and start a stronger one. Hold the screen to boost gravity.

Made as a test task in a single 24-hour window with AI agents: Claude Code for design, balance and review, Antigravity for code. Built with Phaser 4 and TypeScript.

Notes: this is a prototype, not a commercial game. The "ads" (optional rewarded x2 boosts) are simulated; there is no ad network. Best on a phone in portrait. Progress is saved in your browser. Settings → Debug skips to later cycles.
