Move: mouse · drag anywhere (touch) · WASD / arrows (Shift = precise). Only the white dot in your ship can be hit.
Graze: brush close past bullets. Grazes fill the bar under your multiplier (top right); fill it to go up a level. Stop grazing and it drains.
Score grows with your multiplier and fills the augment bar (top left). Every time it fills, you pick an augment. When a card says ▲ UPGRADE, it improves one you already have.
Turrets ◆: circle inside the ring to drain one. A silenced turret charges a phase battery. Draining also defuses mines and overloads boss cores ⬡.
Phase (click · Space · ⚡): half a second of invincibility in slow motion. Everything you pass through is a perfect graze.
Slow time (hold right-click · Shift · ◷): spends your slow bar. Gold shards, cleared surges and bosses refill it.
Guard ◯: forgives one hit per run. Aegis shields break before it.
Goal: each stage ends with a surge and a boss. Hurt bosses by grazing them and their bullets, draining their cores ⬡ and phasing through them. Beat 4 bosses to win.
