The rivals identified
The Nemesis
- -
Weaker sentiment at 35/100 — but still a direct threat
- -
Maintains a high-frequency release cadence of five updates in six months to keep content fresh
- -
Deepens the roguelike experience with extensive weapon variety and character classes beyond basic tower traversal
Contenders
Integrates narrative-driven story modes that provide a more structured progression than the target's roguelike loop
Leverages a proven studio brand to maintain consistent engagement through frequent seasonal event updates
Peers
Features a massive user-generated content ecosystem that provides infinite replayability beyond the base game levels
Utilizes a rhythm-synced level design that creates a distinct sensory experience compared to standard roguelikes
Prioritizes minimalist, high-fidelity art and dynamic weather systems to differentiate from pixel-art roguelike aesthetics
Focuses on a 'zen' gameplay loop that contrasts sharply with the target's combat-heavy tower escape
Employs physics-based movement and cloning mechanics that offer a unique puzzle-platforming challenge
Supports local multiplayer, allowing for a social gaming experience that the target app currently lacks
Super Cat Tales 2
★4.8 (165.5K)Gionathan Pesaresi
📈Offers a character-driven, exploration-heavy platforming experience within the same indie-game ecosystem.
Utilizes a unique touch-based control scheme that simplifies platforming for mobile-first user experiences
Features a non-linear exploration structure that encourages backtracking and discovery over the target's vertical descent
New Kids on the Block
Implements a fast-paced, swipe-to-move mechanic that creates a more frantic, arcade-style vertical descent
Aggressively updates with new challenges and seasonal content to maintain high daily active user retention
The outtake for Once Upon a Tower
Strengths to defend, gaps to attack
Core Strengths
- Offline-first architecture captures travel-heavy user segments
- Princess-led narrative differentiates from standard knight-rescue tropes
Critical Frictions
- Broken ad-removal purchase logic triggers refund requests
- Technical instability on the latest version causes crashes
- Procedural generation logic creates unfair difficulty spikes
Growth Levers
- Expand content variety with new maps to reduce repetition
- Introduce character customization to drive IAP revenue
Market Threats
- Soul Knight's high-frequency update cadence drains player attention
- Tomb of the Mask's arcade-style descent captures casual funnel
What are the next best moves?
Audit ad-removal purchase logic because users report it fails to stop ads → reduce refund surge
Ad-removal purchase failure is a top complaint theme causing revenue friction.
Trade-off: Pause the new map development sprint — revenue stability takes precedence over content expansion.
Stabilize loading process because crashes are the #2 complaint theme → improve retention
Technical instability post-update is eroding user trust.
Trade-off: Deprioritize character customization features — stability is the current churn risk.
A counter-intuitive read
The game's reliance on offline play is its primary moat, yet the team's focus on procedural generation is a distraction from the stability required to keep that moat defensible.
Feature Gaps vs Competitors
- Multiplayer co-op (available in Soul Knight but absent here)
- Character classes (available in Soul Knight but absent here)
Key Takeaways
The game holds a loyal base through its addictive offline loop, but broken monetization and technical instability are driving churn, so the PM must prioritize purchase-flow audits and crash stability to protect the revenue baseline.
Where Is It Heading?
Mixed Signals
The casual roguelike market is consolidating around high-frequency update cycles, leaving this app exposed. Without addressing the technical regressions and monetization friction, the current loyal base will migrate to more stable, content-rich alternatives.
Technical instability in the latest release causes crashes, which erodes the daily active habit and compounds the rating drag.
Broken ad-removal purchases frustrate users, leading to negative sentiment and potential refund surges that compress monetization efficiency.
