At the end of the universe, you pilot the Graph Theory to crisscross spacetime, fending off strange matter creatures and reversing Earth’s fate. This isn’t just tower defense—it’s a strategic roguelike where every node placement, power distribution, and heat management decide survival. And there are no upgrades outside of each run; beating the game on your first run isn’t locked behind player stat checks. Key Features: Complex Hardcore Strategic Gameplay - With randomized and limited resources, build wisely. Spacetime Locations - From the end of time to the orbit of a neutron star, with different types of enemy forms. Build Variety - Towers can have different upgrade directions, changing their functionality—transforming them into support or primary DPS. Place nodes and towers in a graph-theory manner. Co-pilot - Choose a character to accompany you (currently only 1 is available). Permadeath Roguelike - If the Graph Theory fails, your consciousness will be transmitted back to the end of time.
