Sphere Defense: A Minimalist Tower Defense Gem Launches on Mobile

Developer Tomoki Fukushima has released Sphere Defense, a captivating tower defense game where players protect Earth from waves of enemies. While the core gameplay remains true to the tower defense genre—strategic unit placement and resource management are key to survival—Sphere Defense distinguishes itself with its minimalist aesthetic and vibrant neon visuals.

The game challenges players to strategically position towers and units to repel incoming attacks. Each successful defense earns resources used to upgrade units and achieve victory. Difficulty progressively increases, rewarding players who complete levels without taking damage with high scores.

Fukushima cites geoDefense, a tower defense game by David Whatley, as inspiration. He was impressed by its simple yet engaging and beautiful design.
