By Erabit Studios

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.

  • Features a multi-character progression system that allows for deeper RPG-style customization than this app'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 this app's darker, more industrial visual theme.

The Analyst's Read

Key takeaways for Monster Train+

Where is it heading?

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.

The SWOT

Core Strengths
  • Vertical lane defense mechanics differentiate from standard 2D roguelikes
  • Clan-based progression provides high replayability for core strategy enthusiasts
Critical Frictions 2 weaknesses inside
Growth Levers
