How the game changes

  • Default settings provide 297 checks across 48 levels: clears, 69 cousins, 39 presents and 141 crowns. Planet rewards on clears are an optional fixed local category.
  • Collectionsanity offers either 3,637 eligible individual objects or configurable milestones. The full catalogue lists both possibilities separately; they are never enabled together.
  • 173 possible reward identities include level and cousin unlocks, cosmetic presents, Planets, Stardust, regular and super freebies, and three traps. No progressive item chains are defined.
  • Gather Planets to unlock That Hole..., then plug the hole. Easy Finale is enabled in the plugin by default and is assumed by the World’s logic.
Explore game mechanics

Before you start

  • Use the matching v0.3.0 APWorld and plugin. The World requires Archipelago 0.6.7; the client advertises protocol version 0.6.6. The documented loader is BepInEx 6 IL2CPP build 783. Unix support is described through Wine/Proton, without an independent runtime test here.
  • A catalogue entry is not a promise of inclusion: level exclusions, Skip Tutorial, collection mode and milestone settings change checks. The collection modes are mutually exclusive. Forced local Stardust checks cannot hold progression.
  • When clear Planets are enabled, the percentage-goal denominator adds non-starting level unlocks rather than all fixed Planet checks. With defaults this computes 73 required from a modeled 122, although 128 Planets are placed across the pool and clear checks.
  • Limited reward space reduces requested pool Planets first and can then omit cousin/present cosmetics. Starting levels and the starting cousin are randomly selected.
  • The native client has no reconnect path without restarting the game. Keep Easy Finale on and start a fresh save. Displayed level positions can be displaced; the maintainer documents selecting their intended location or reloading the scene. No full playthrough or native rebuild was performed.
