Sinistar

Arcade shooter where you pilot a lone ship mining crystals from floating planetoids to build Sinibombs—the only weapon capable of destroying Sinistar, a giant skull-faced enemy ship under construction by worker drones. You shoot rocks to release crystals, but blast too hard and the planetoid shatters, leaving nothing behind. Enemy ships try to steal your crystals while you gather enough to craft bombs. The game cycles through four zones (Worker, Warrior, Planetoid, Void), each changing what you face. Once Sinistar finishes building itself, it actively hunts you down while you scramble to finish bombing it. Fast reflex shooting mixed with resource management—you're racing the clock and dodging attacks simultaneously. Fits players who want twitchy arcade action with a layer of tactical collecting.
