Sphere Defense: A Minimalist Tower Defense Experience Now Available
Developer Tomoki Fukushima has released Sphere Defense, a new tower defense game for mobile devices. The game tasks players with defending Earth from waves of enemies using strategically placed units.
While the core gameplay remains true to the tower defense genre – strategically positioning units, collecting resources for upgrades, and navigating increasing difficulty levels – Sphere Defense distinguishes itself with its minimalist aesthetic and vibrant neon visuals.
Success in each level rewards players with resources to upgrade their defenses. Perfect runs, achieved without taking any damage, lead to high scores and bragging rights.

Fukushima cites the classic tower defense game geoDefense by David Whatley as inspiration, highlighting its simple yet engaging and visually appealing design.
