Initially resembling light-hearted action platformers, Another Crab's Treasure surprises players with its serious Soulslike game mechanics that focus on defeating challenging bosses through mastery and rhythmic combat. The game's combat style shares similarities with Sekiro more than Dark Souls, requiring a reactive and aggressive approach.

Developing a combat system for a hermit crab protagonist posed challenges for Aggro Crab, leading to a gameplay centered around blocking and parrying with the shell. The emphasis on these defensive moves over dodging aligns the game closer to Sekiro's combat philosophy.

One significant departure from traditional Soulslike games is the absence of a stamina system in Another Crab's Treasure, favoring a faster-paced gameplay style where players can attack without limitations. This shift introduces a new level of risk and rewards players for strategic decision-making during combat.
