- Community Price:
  - Community fair range: $5.00 - $7.00
  - Reasoning: The community feedback indicates that the game is considered fairly priced around 800 yen (~$5.3) and under €7 (~$7.5). One review explicitly states that under €7 is reasonable but not currently worth it, suggesting the fair price may be at the lower end. Another review confirms 800 yen is worth the playtime, and two others affirm the price is fair without specifying an amount. Combining these signals, the community's fair base-game price range appears to be approximately $5 to $7 USD.
- Playtime Metrics:
  - Game completion: 1.5h
  - Story completion: N/A
  - Session length: 1.0h
  - Endgame: N/A
  - Reasoning: The evidence indicates that the main game can be completed in roughly 1–2 hours, with multiple players reporting completion in under an hour and one reporting about 2 hours, so gameCompletion is estimated at 1.5 hours. Session length is described as short and quick, with runs typically lasting around 30 minutes to an hour, supporting a sessionLength estimate of 1 hour. No evidence supports story completion or a distinct endgame phase, so those metrics are null.
