Gemini 4 Carbon High Builds Playable Browser Game

This is a compelling capability demo, but not yet proof of superior game-building reliability: the prototype plays, while balance and long-horizon completion remain untested.

• –Demonstrates end-to-end generation from a broad prompt to a playable artifact.
• –Tests genre fusion, progression design, visuals, controls, and gameplay logic simultaneously.
• –Reaching Wave 2 confirms basic functionality but says little about full-campaign balance.
• –Results reflect Gemini 4 Carbon High plus Antigravity’s execution environment, not a raw API-only comparison.
• –The practical developer signal is strong: rapid playable prototypes could compress ideation and QA cycles.
