Starspire Keep

Starspire Keep is a cozy isometric base-builder set on a small green island ringed by shallow water. Your Castle stands at the center, surrounded by a Gold Mine, a glowing purple crystal well, a wooden watchtower, a domed storehouse, and a blue-roofed barracks where little shield-bearing soldiers wait for orders.

Tap the resource bubbles that pop up over your buildings to gather gold and purple crystals, then spend them to build and decorate. Keep an eye on your storage caps, your gem count, and your builders, since each builder can only work on one project at a time. Royal Decrees guide you with simple goals and reward you with gems.

When your troops are ready, hit Attack! to send them into battle, then come back to keep expanding your keep. It all runs in a single HTML file built with Three.js. Every model, texture, sound, and music track is generated in code, and the game plays comfortably on mobile.
