Tips

Customize your loadout: Before starting, choose “Edit Mode” to build a custom weapon array that fits your playstyle, such as combining the Ripple Laser with Option familiars.
Get Options early: Options are glowing orbs that follow your ship and copy your attacks. Prioritize getting them early to dramatically increase your firepower and screen coverage.
Watch your speed: Upgrading your speed once or twice is essential for dodging enemy fire, but upgrading it too many times will make your ship uncontrollably fast and prone to crashing.
