ORBIT — double-click/tap a nearby planet to orbit. Your ship circles automatically, gathering crystals and resources. Shields recharge fastest while orbiting (8/s vs 3/s cruising, 0 in combat). Thrust or fire to break orbit.

SHIELDS — protect from radiation zones and reduce collision damage to almost nothing. Recharge faster when not in combat.

RADIATION ZONES — green/yellow hazard areas. Without shields they drain your hull at 5 hp/s. With shields you're safe, and rare weapon drops are 3× more common inside.

FUEL — shoot asteroids, orbit planets, or skim their rings. Bank cargo at the home beacon. Below 10% = melt prompt. Empty = self-destruct.
LOOT — shoot debris/crates; hover 2s over wrecks to salvage.
