Quick notes

  • Power Eggs fund campaign improvements. Collect eggs in stages and spend them on available Hero Mode upgrades.
  • Sunken Scrolls record hidden discoveries. The campaign includes scrolls in its regular stages and after bosses.
  • Upgrade the tool causing the problem. A stronger Hero Shot helps against targets, while a larger ink supply makes sustained movement and bomb use easier.
  • Check the stage record before replaying. Use the campaign’s progress display to identify a missed scroll.
