STARLIGHT SURGE

STARLIGHT SURGE

A neon-drenched space shooter where every kill chains into the next. Survive endless waves of cosmic enemies, chase explosive combo multipliers, and battle colossal warship bosses — all backed by a procedurally generated chiptune soundtrack that shifts from uplifting major keys to tense minor sections as the action intensifies.

★ FAST. FRENZIED. FANTASTIC. ★

Pilot your starfighter through an escalating onslaught of alien drones, zigzagging crystal shards, armored fortresses, and screaming speeders. Chain kills within 2 seconds to build your combo multiplier — x20 means 20× points per kill. Let the chain break and watch your score evaporate.

Every 5 waves, a BOSS appears: a massive warship with three rotating attack patterns (spread shot, aimed volleys, circular burst). As you damage it, armor cracks appear, its core becomes exposed, and attacks accelerate. Defeat it for guaranteed triple power-ups.
