Chapter Progress Checklist

Endacopia is a four-act structure with lots of checkpoints inside each act. This checklist lets you tick off every milestone as you play, then look back and see exactly which run you are on. Use it side-by-side with Walkthrough and 100% Completion.

The general advice is to save at every wandering disk before any of the bolded milestones below — once you cross a bolded line, you may need to reload an earlier save to recover. See Save System for save slot limits.
