The rivals identified
Nemeses(1)
This title is the most direct thematic rival, mirroring the roguelike deckbuilder structure with a focus on character-specific skill trees and multi-class progression.
Differentiators
- Features a multi-character progression system that allows for deeper RPG-style customization than the target's clan-based model.
- Integrates a talent tree system that persists across runs, providing a sense of long-term character growth.
- Offers a more stylized, hand-drawn aesthetic that differentiates it from the target's darker, more industrial visual theme.
Head to head
The target app should lean into its superior mechanical balance and production quality to retain core fans, while potentially exploring lighter meta-progression elements to compete with the retention-focused design of Indies' Lies.
Contenders(3)
A direct competitor in the mobile roguelike deckbuilder space with a focus on traditional dungeon crawling.
Differentiators
- Combines traditional turn-based RPG exploration with deckbuilding, offering a more classic dungeon-crawler feel.
- Features a more traditional inventory and equipment system that adds a layer of gear-management strategy.
Shares the core roguelike deckbuilding DNA but differentiates through a unique 'hit-or-stand' combat mechanic.
Differentiators
- Integrates a blackjack-inspired combat mechanic that forces players to balance risk and reward differently than standard deckbuilders.
- Focuses on a sci-fi setting and character-class variety that appeals to a different aesthetic preference than the target's dark fantasy.
A highly focused roguelike deckbuilder that competes directly for the same 'quick-session' mobile audience.
Differentiators
- Utilizes a simplified swipe-based interface that is significantly more accessible for short, mobile-first play sessions.
- Features a distinct, minimalist art style that prioritizes readability and speed over the target's complex, multi-lane board.
Same space(2)
A massive player in the card game category that focuses on competitive PvP rather than the target's solo-focused roguelike loop.
Differentiators
- Focuses heavily on competitive PvP and tournament-style play, contrasting with the target's PvE roguelike experience.
- Utilizes a complex, established rule set from a physical card game that requires significant player investment to master.
Dominates the broader digital card game category, serving as the primary benchmark for monetization and live-service operations.
Differentiators
- Operates as a massive live-service platform with constant expansion releases and a highly competitive ranked ladder system.
- Leverages a massive, established IP and brand ecosystem that creates a significant barrier to entry for smaller titles.
New entrants(1)
An emerging threat that has redefined mobile card game pacing with 3-minute matches and high-velocity updates.
Differentiators
- Pioneered a 'snap' betting mechanic that introduces high-stakes psychological warfare into every short-form match.
- Maintains an aggressive, high-frequency update cadence that keeps the meta-game shifting constantly for the player base.

The outtake for Monster Train+
Strengths to defend, gaps to attack
Core Strengths
- Vertical lane defense mechanics differentiate from standard 2D roguelikes
- Clan-based progression provides high replayability for core strategy enthusiasts
Critical Frictions
- Unreliable iCloud sync causes progress loss for multi-device users
- Lack of native controller support limits input precision for long sessions
Growth Levers
- Meta-progression systems could bridge the gap to casual player retention
- Untapped B2B education partnerships for strategy-based learning
Market Threats
- MARVEL SNAP's high-frequency update cadence shifts player expectations
- Indies' Lies' permanent talent tree progression siphons long-term engagement
What are the next best moves?
Rebuild iCloud sync logic because sync failure is the top-cited churn risk → improve multi-device retention
User sentiment data identifies iCloud sync as the primary technical friction point.
Trade-off: Pause the next content-expansion sprint — sync stability is a prerequisite for long-term player retention.
Ship native controller support because it is the top-requested feature → increase session length for power users
Review data shows consistent demand for console-like input methods.
Trade-off: Delay the UI polish pass on the main menu — controller support provides higher utility for active players.
A counter-intuitive read
The reliance on manual cloud-save triggers is a hidden retention moat for single-device players, as it forces a deliberate session-end habit that prevents accidental data overwrites.
Feature Gaps vs Competitors
- Permanent meta-progression talent trees (available in Indies' Lies but missing here)
- Native controller support (available in most PC-to-mobile ports but missing here)
Key Takeaways
Monster Train+ holds its category lead through sticky mechanical depth but bleeds multi-device players to sync failures, so revenue growth hinges on stabilizing the cross-device experience before expanding content.
Where Is It Heading?
Stable
The roguelike deckbuilder market is consolidating around titles that offer both deep mechanical loops and high-frequency meta-progression updates. Monster Train+ remains advantaged by its high-fidelity production values, but the lack of permanent progression leaves it exposed to rivals like Indies' Lies, so the PM must prioritize technical stability to retain the current core base.
Persistent iCloud sync failures erode the daily active habit for multi-device users, which compounds the rating drag already visible on Android.
Recent grossing rank gains in the US and SK indicate the core roguelike loop remains highly effective at driving IAP revenue.
