Casey Yano, co-founder of Mega Crit Games, discussed the development of the sequel to Slay the Spire in an interview with Edge magazine. He cited the Dark Souls series as a key inspiration, particularly in terms of character building and player choice. Feedback from playtesters led the team to reevaluate their initial ideas, resulting in a more nuanced approach that retains core mechanics while introducing new features. Despite some criticism regarding recent updates, Yano indicated that the sequel will continue to evolve based on player feedback, similar to the original game's seven years of post-launch support. He also confirmed that the game will maintain a definitive endpoint, expressing skepticism about the inclusion of an 'infinite mode' due to concerns that it could diminish the excitement of deckbuilding.
