A 2D pixel-art score-chaser built on real orbital mechanics. Launch, pitch over, coast, and circularise into the exact orbit each contract asks for, then hold it for one full lap before the fuel runs out. Ten missions, three hulls, and a gold tier tuned past the developers' own autopilot.

In 方块战舰：Module Warship, you command the fleet and design the ships.This 2D space sandbox rejects pre-set hulls, offering extreme DIY freedom instead.
