Description
Sphere Defense is a tower defense game for Wear OS. Defend the core. Two simultaneous controls. Survive the wave.
Your core sits at the center of the play area. Three rings of defense ripple outward around it. Enemies stream in from the bezel — basic red ones, slow heavy orange tanks, and fast blue sprinters. They all want to reach the core. None of them should.
The crown rotates a glowing shield arc around your core at a fixed orbit distance. Position it to deflect incoming enemies away. The shield doesn't destroy — it bounces. Tap anywhere to fire a bullet in the direction your shield is currently facing. The bullet kills. Combine the two.
It sounds simple. It isn't, by wave 4.
Every 10 kills grants a bomb. The next tap detonates it: every enemy on screen vanishes in a yellow shockwave. Bombs are limited — save them for the moments you can't.
Adaptive difficulty: each wave brings more enemies and faster ones. Tank spawns kick in at wave 2, sprinters at wave 3. The combo multiplier scales your score from x1 up to x8 when you keep killing.
Features • Twin-input controls: crown for defense, tap for offense • Three enemy types with distinct speed/health/value (red/orange/blue) • Wave-based progression with adaptive enemy mix • Combo multiplier up to x8 • Bombs earned every 10 kills (screen-clearing AOE) • Particle effects on every hit/deflect/kill • Hearts-based health (3 hits before game over) • Persistent high score • Standalone — no phone required • No ads, no IAP, no internet permission
Controls • Crown rotates your shield around the core • Tap → fire forward (or detonate a bomb if you have one) • Tap on Game Over → restart
Tips • Tanks (orange) need 3 hits but score 30 points. Whittle them down with the shield while shooting other enemies. • Don't waste bombs on a single enemy — wait for the cluster. • Sprinters are scary — use the shield to deflect rather than risking a missed shot.
Built for Wear OS 3+. Standalone, offline, no tracking.
The watch is the only device where a single hand controls two inputs at once with this much precision. The crown is your shield, your finger is your trigger. That feeling is the game.
