  • +you like learning about characters through story events
  • +you want a sci-fi mystery told across time loops

Not for you if...

  • −you want to debate with other human players
  • −you prefer continuous storytelling over repeated deduction rounds
  • −you dislike stats affecting your ability to persuade others

What players say

93% of 5,131 reviews are positive · 88% of 45 in the last 30 days

Players praise the cast, sci-fi story, art, and music. Their most common complaint is that debates repeat stock dialogue, while story events can take many loops to appear. Some say votes feel driven more by stats or unpredictable crew behavior than by deduction.
