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

- [ ] [INVEST] Ship cloud-based account linking because it is the top-requested missing feature → unlock data-loss frustration
<!-- /section:pm-actions -->

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


- Cloud-based account linking (available in Epic Seven but missing here)
<!-- /section:feature-gaps -->

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

The anime RPG market is consolidating around high-fidelity titles with rapid update cadences, leaving SLIME-ISEKAI Memories exposed due to its maintenance-mode release velocity. Without a shift toward technical stability and modern account management, the app will continue to lose its core fan base to more responsive competitors.

- 🔴 Frequent application crashes during combat sequences erode the daily active habit, which compounds the rating drag already visible on Android.
- 🔴 The lack of standard cloud-save infrastructure causes preventable churn, as users report losing progress during device changes or reinstalls.
