<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [MAINTAIN] Audit technical compatibility with current iOS versions because the app is currently unplayable for many users → restore baseline functionality
<!-- /section:pm-actions -->

<!-- section:feature-gaps -->
### Feature Gaps vs Competitors


- Cross-platform play (available in The Past Within Lite but absent here)
<!-- /section:feature-gaps -->

<!-- section:outlook -->
### Outlook: Declining

The puzzle adventure market is shifting toward titles with high-frequency updates and social features, leaving legacy ports like Riven: The Sequel to Myst JP increasingly isolated. Without a technical refresh, the app will continue to lose its remaining user base to modern, free-to-play competitors.

- 🔴 The lack of technical updates since 2022 erodes user trust, leading to negative sentiment and poor ratings for the current version.
