Engage in Galactic Combat: Sphere Defense Protects Earth

Outsmart relentless enemy waves and defend the sphere in Sphere Defense, a new tower defense game from developer Tomoki Fukushima. This isn't your average tower defense game; its minimalist aesthetic, accented by vibrant neon lights, sets it apart.

The core gameplay remains true to the genre: strategically position your units and towers to repel incoming attacks. Each successful defense earns you resources to upgrade your units, pushing you closer to victory. Difficulty ramps up with each level, rewarding skillful players with high scores for bragging rights – perfect for those who can achieve a flawless run.

Fukushima explains the inspiration behind the game: "This game is a tribute to 'geoDefense', a tower defense game created over a decade ago by David Whatley. 'geoDefense' captivated me with its simple yet engaging and visually appealing design."
