Geomeria is a browser game I created, combining resource mining, energy networks, and geometric tower defense.

Mine, connect, and defend
After a three-dimensional universe collapses into two dimensions, players command the Geometric Ark: mine energy, connect buildings, and build defenses to survive rising entropy.
Buildings must connect to the Ark’s energy network to operate. As deposits run dry, players expand outward and use geometric formations to strengthen their defenses, balancing resource gathering with defensive layouts.
The game is free to play in a browser without signing up, on desktop and mobile.
