Sphere Defense

Tower defense for Wear OS. Crown rotates your shield. Tap to shoot. Survive.

Action Tower defense Crown

Your core sits at the centre. Enemies stream in from the bezel — basic red, slow heavy orange tanks, and fast blue sprinters. The crown rotates a glowing shield arc around your core; tap to fire a bullet in the direction the shield is facing. Two inputs, both used at once.

The shield doesn’t destroy — it bounces. The tap kills. The combination is the whole game: hold the shield against a tank while picking off sprinters with bullets, sweep the shield through clusters to deflect them away from the core, save your bullets for the ones too fast to bounce.

Every ten kills earns a bomb — your next tap detonates everything on screen. Bombs are limited; save them for the moment you can’t. Adaptive difficulty pushes spawn rate and enemy mix higher each wave. Combo multiplier scales from x1 to x8 when you stay alive.
