Comparable or better than Slay the Spire: Many players find this game to be on par with or superior to Slay the Spire, citing reduced RNG, more depth, and a unique identity. It is often called a true successor to the genre's benchmark.

Common complaints

Game is overly complex and unintuitive: Multiple clusters highlight that the game's complexity and lack of intuitiveness make it difficult to pick up and understand. The convoluted gameplay systems and poor intuitiveness confuse players initially.

Very steep learning curve: Several clusters mention a steep learning curve due to many rules and keywords, making the game harder to learn compared to similar titles. This is a common barrier for new players.

Not beginner friendly: The complexity and numerous concepts make the game difficult for newer players to get into. It is less approachable and harder to pick up than other games in the genre.

Less appealing than Slay the Spire: The game's worldbuilding, presentation, and elegance are seen as inferior to Slay the Spire, and it lacks the simplicity and appeal of that title. This comparison negatively affects its reception.

Runs last too long: Players report that runs can last anywhere from 1.5 to 3 hours, which is considered too long for a game session. This length may discourage repeated playthroughs.

Gameplay and performance

Discard cards for energy: Players can discard cards from hand to gain energy, a core resource mechanic. This allows strategic sacrifices for more actions.

Roguelike deckbuilder gameplay: The game is a roguelike deckbuilder resembling Slay the Spire. It features card-based combat and randomized runs.

Similar to Slay the Spire: Players frequently compare the game to Slay the Spire, noting similarities but also unique twists. It's often described as more complex or skill-expressive.

Cards and energy persist: Unused cards and energy carry over between turns, allowing long-term planning. This deviates from typical deckbuilders.

Socket void stones into cards: Cards can be enhanced by embedding void stones, which add effects and customization. This provides a deep modding system.

Frequent crashes and instability: Multiple players mention frequent crashes, random crashes, and general instability, making the game difficult to play reliably.

Steam Deck performance varies: Players report that the game works perfectly on Steam Deck, but others experience bugs. This inconsistency suggests compatibility issues that need addressing.

Game fails to launch: One player reports the game does not start at all. This is a critical issue preventing gameplay entirely.
