AYE.GG / HARBOR DEFENSE
Four bright piers. One giant protector. No rescue left behind.
Catch pods and stop drones before they reach the city.
Use Left/Right or A/D to change piers. Press C to catch a rescue pod, Space to punch a drone, R for a charged roar, and period to wait. Every move or action spends one beat. Normal pods and drones begin five beats away; armored drones need two punches and begin six beats away. A full roar meter stops any drone from any pier, but cannot catch a pod. The city can absorb two misses; a third ends the wave.
Best beats on this stage: —. Progress saves on this device.
Cyan rescue pods need a catch. Coral drones need one punch. Gold armored drones need two punches. The large countdown shows how many actions remain before impact.
Moving one pier costs one beat, just like attacking. Start toward the next lane early, but do not punch a pod or try to catch a drone: the wrong action still spends time.
Every four successful catches or final punches fills the roar meter. A roar destroys the current drone from anywhere, so save it for a far-away armored threat. Rescue pods still require a careful catch.
All 50 deterministic waves are playable with touch or keyboard. Later stages run longer, change lanes more sharply and deploy more armor, but every event leaves enough time for a perfect response.
