Galaxy Miner
Galaxy Miner is a real-time multiplayer space mining game built entirely with vanilla JavaScript — no frameworks. Players mine resources across a procedurally generated galaxy, trade on a player marketplace, build fleets, and battle NPC factions with distinct AI strategies ranging from flanking pirates to a phase-based queen boss.
