## Description

Sphere Defense is a tower defense game for Wear OS. Defend the core.<br>Two simultaneous controls. Survive the wave.<br><br>Your core sits at the center of the play area. Three rings of defense ripple<br>outward around it. Enemies stream in from the bezel — basic red ones, slow<br>heavy orange tanks, and fast blue sprinters. They all want to reach the<br>core. None of them should.<br><br>The crown rotates a glowing shield arc around your core at a fixed orbit<br>distance. Position it to deflect incoming enemies away. The shield doesn&#39;t<br>destroy — it bounces. Tap anywhere to fire a bullet in the direction your<br>shield is currently facing. The bullet kills. Combine the two.<br><br>It sounds simple. It isn&#39;t, by wave 4.<br><br>Every 10 kills grants a bomb. The next tap detonates it: every enemy on<br>screen vanishes in a yellow shockwave. Bombs are limited — save them for<br>the moments you can&#39;t.<br><br>Adaptive difficulty: each wave brings more enemies and faster ones. Tank<br>spawns kick in at wave 2, sprinters at wave 3. The combo multiplier scales<br>your score from x1 up to x8 when you keep killing.<br><br>Features<br>• Twin-input controls: crown for defense, tap for offense<br>• Three enemy types with distinct speed/health/value (red/orange/blue)<br>• Wave-based progression with adaptive enemy mix<br>• Combo multiplier up to x8<br>• Bombs earned every 10 kills (screen-clearing AOE)<br>• Particle effects on every hit/deflect/kill<br>• Hearts-based health (3 hits before game over)<br>• Persistent high score<br>• Standalone — no phone required<br>• No ads, no IAP, no internet permission<br><br>Controls<br>• Crown rotates your shield around the core<br>• Tap → fire forward (or detonate a bomb if you have one)<br>• Tap on Game Over → restart<br><br>Tips<br>• Tanks (orange) need 3 hits but score 30 points. Whittle them down<br>  with the shield while shooting other enemies.<br>• Don&#39;t waste bombs on a single enemy — wait for the cluster.<br>• Sprinters are scary — use the shield to deflect rather than risking<br>  a missed shot.<br><br>Built for Wear OS 3+. Standalone, offline, no tracking.<br><br>The watch is the only device where a single hand controls two inputs at<br>once with this much precision. The crown is your shield, your finger is<br>your trigger. That feeling is the game.
