You are the reactor of a far-future hull. One layer of plate is the only armor. Each wall cell takes three hits. The core takes one. If a shot finds the light, it is over.
Tetris plates drift and fuse on contact — more armor, more mass, less speed. Dead-still modules in the dark become turrets, thrusters, speed coils, force fields, grabber claws, batteries, generators, and rare missile racks. The core ticks +1 energy every 3 seconds; generators add more. Star motes fill batteries. Combine two of the same rank to climb 2–5.
WASD to fly. Left click lasers. Middle click missiles — slow, blasting, they pry plates off or wreck them. Hold right click to grab. Space burns thrusters. Scroll to zoom. M mutes.
