⚡ Abilities

  • Every character has unique abilities based on their series and role.
  • Transform into a mermaid when underwater, in rain, or exposed to Moon Water (rain disables positive status effects).
  • Swim faster underwater — hold C while swimming.
  • See the current moon phase by right-clicking on a bed.
  • As a mermaid on land, you move slowly and need to "melt" back into human form (not possible in cold biomes).
  • After drying off, a "Drying..." progress bar is displayed on screen during the 5-second transformation back to human form.
  • Unlock many new achievements.

🐉 Water Dragon

  • The Water Dragon has a custom pixel-art boss health bar displayed on screen.
  • Getting hit once removes your mermaid form.
  • Hit as a half-mermaid → powers removed. Hit as a full mermaid → instant death.
  • Turn the Tide (Zac & Weilan — B key): 5 seconds of immunity against the Water Dragon.

🌕 Moon Events

  • Rikki sets nearby things on fire during a full moon (she gains fire resistance during this time).
