My Only Heroes is a single-player roguelite deckbuilder game in which players assemble a squad of heroes, each represented by a card in their deck, and navigate through procedurally generated dungeons. In this game, players start each run with a random set of recruits, aiming to unlock powerful Main Heroes with enhanced abilities as they progress through the shifting dungeon environments to reach Mayhem Mountain. It stands out with its stylized, colorful hand-drawn art style, anime-inspired character designs, and advanced gameplay elements such as stacking equipment for strategic combos, turn-based combat mechanics, and a focus on deck-building and strategic decision-making.
