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 relentless enemy waves. 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 used to upgrade your defenses, leading to ultimate victory. The challenge intensifies with each level, rewarding skillful players who can complete levels without taking damage with high scores.

Fukushima cites the classic tower defense game geoDefense by David Whatley as a major inspiration, praising its blend of simplicity, fun, and beauty.
