Nelumbra is a 2.5D time-survival RPG where you play as the Light Bearer, a savior trapped in endless time loops who must discover their destiny while battling relentless celestial enemies. Each loop offers the chance to survive longer, unlock new characters, and upgrade your abilities as you fight to either escape the loop or be trapped forever. The game features an auto-attack that can be upgraded between loops to suit your playstyle, as well as a shooting gallery mechanic that lets you rip through hordes of enemies while creating dynamic synergies with your build.
