In this video, we put Google Antigravity and Gemini Pro through a real developer test by building a full LEGO-style 3D game using mainly ReactJS, Vite, and TypeScript.

There’s been a lot of hype around Antigravity and Google’s new Gemini Pro model… but instead of talking about it, we’re actually using them to see how they perform in a real build. You’ll see how well Gemini Pro 3 handles complex tasks such as building a 3D Lego simulator, how it handled bugs and more! We'll be deep diving into Antigravity to do just that - can the new AI IDE from Google compete with Cursor? (My current favourite IDE)...

We'll find out together! - Here's what you’ll see in this video:
✅ Hands-on demo of Google Antigravity as I build a full Lego 3D block simulator game
✅ Using Antigravity & Gemini Pro for real world complex coding 3D modelling tasks
✅ My Honest thoughts on Antigravity.
✅ Full Antigravity & project walkthrough + live deployment of the app with Hostinger
