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 objective is straightforward: strategically position your towers and units to repel incoming attacks. Each successful defense earns resources, allowing for unit upgrades and improved defenses. The difficulty progressively increases, challenging players to master their strategies. Perfect runs, achieved without taking any damage, yield high scores and bragging rights.

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