Please include your device model, iOS or iPadOS version, app version, and a short description of what happened. Screenshots or screen recordings help when reporting visual or gameplay bugs.

Controls

Drag anywhere on the screen to move the ship. The ship does not jump to tap locations, which keeps movement precise during dense patterns.

Hitbox

Only the red core takes damage. Wings, glow, trails, and the rest of the ship are visual so the game can look dramatic while staying fair.

Phase Pulse

Graze bullets to fill the Phase Pulse meter. When it is ready, activate it to clear danger around the ship and recover control of the screen.

Leaderboards

Game Center supports weekly and all-time high score competition when the player is signed into Game Center on the device.

Progress

Boss unlocks, settings, ranks, and local best scores are stored on the device. Reinstalling the app may remove local-only progress.

Troubleshooting

If the game feels slow, close background apps, restart the device, and make sure the latest app version is installed. Report persistent issues by email.
