The Eternal Spiral features challenging combat reminiscent of the Dark Souls series, emphasizing precise timing and strategic decision-making. Players must survive three intense waves of enemies, each culminating in a unique and formidable miniboss. Upon victory, the player progresses to the next level and gains a minor buff for the time being.

The game?s innovative time loop mechanic ensures that each reset brings both familiarity and new challenges. The player retains the skills and experiences gained from previous cycles, allowing players to adapt their playstyle and unlock new abilities.
However, The Big Boss becomes increasingly cunning, introducing unpredictable elements to each encounter.
