The Nemesis
Dolphin Simulator
★3.7 (981)Gluten Free Games LLC
This app competes for the same aquatic-themed audience by offering a high-fidelity simulation experience that challenges Aquapolis's narrative-driven city building.

The outtake for Aquapolis - city builder game
Strengths to defend, gaps to attack
Core Strengths
- Narrative-driven quest system sustains session frequency
- 80+ unique building assets provide visual variety
Critical Frictions
- Frequent crashes during startup and play
- Aggressive repair-cost monetization
- No cloud-save functionality
Growth Levers
- Expand land area for decoration
- Implement non-Facebook social connectivity
Market Threats
- High-fidelity simulation rivals like Dolphin Simulator
- New entrants using Gacha monetization models
What are the next best moves?
Audit crash logs because stability is the #1 complaint → reduce churn
Users report consistent crashing during startup and active play.
Trade-off: Pause the land expansion feature sprint — stability is a prerequisite for retention.
Rebalance repair costs because monetization pressure is the #2 complaint → improve sentiment
Players feel forced to spend currency when machines break down too often.
Trade-off: Same-quarter capacity available — no major lever displaced.
A counter-intuitive read
The lack of updates since 2020 is not a failure but a deliberate strategy to minimize support costs while the game remains profitable through legacy ad-inventory.
Feature Gaps vs Competitors
- Combat and survival mechanics (available in Dolphin Simulator)
- Non-Facebook social visiting mechanics (available in Fish Tales)
Key Takeaways
Aquapolis retains players through a strong narrative hook, but technical instability and aggressive monetization for repairs create significant churn risk, so the PM should prioritize stability fixes to protect the existing user base.
Where Is It Heading?
Stable
The casual city-builder market is consolidating around live-ops heavy titles, leaving Aquapolis exposed due to its lack of recent content updates. The app's reliance on legacy monetization will likely see a slow decline in active users as technical debt accumulates.
Frequent crashes in the latest build erode the daily active habit, which compounds the rating drag already visible on Android.
Recent updates focused on stability, no feature expansion, indicating the app is in maintenance mode.
