Overall, the sentiment towards Shroom and Gloom is largely positive, with players praising its unique art style, innovative dual deck-building mechanics, and atmospheric audio. The game stands out for its engaging and replayable experience, particularly for fans of the roguelike deck-builder genre. However, balance issues and RNG system quirks are common criticisms, and the game does face some difficulty opinions, fluctuating based on player experience with similar games. Despite some early access bugs, the game provides a solid foundation with considerable potential for growth and refinement.
