The game features sexualized content, specifically 'girls in swimsuits', which may be inappropriate for younger audiences. While there are microtransactions, their impact on gameplay is unclear. The game's narrative structure, with multiple endings, could encourage repeated play, though individual sessions are likely short.

- GDPR-K:What Ludograph checks: whether age assurance and consent flows are designed for under-16s, in the spirit of GDPR Article 8.: Estimated from review data. No privacy or child-targeting concerns found.
- ODDS:What Ludograph checks: whether paid random-reward drop rates are disclosed, as required in China, Japan and South Korea.: Estimated from review data. No paid random-reward mechanics found, so drop-rate disclosure requirements do not apply.
