Fly safe, pilots. Or don't—since you have infinite health anyway.

Stars are the primary currency. With a trainer, you can set your stars to 999,999 instantly. This allows you to max out your Ship’s Main Gun, Wing Cannons, Magnet Range, and Health Regeneration before you even finish Stage 3.

Play through on Normal legitimately. Suffer through the grind. Learn the bullet patterns. Once you finish Stage 8 and roll credits, then fire up the trainer. Use it to clean up the ridiculous challenges (like "Stage 6 - No damage, kill all, rescue all") on Insane difficulty.
