Shelldiver is an incremental adventure game that sends players into the depths of the sea, taking on the role of a senior turtle whose business revolves around selling jellyfish. This arcade-style game offers a relaxing experience with its atmospheric setting, cute 2D graphics, and idle mechanics. 

Sell jellyfish to patrons 

Shelldiver puts you in charge of a sleepy but determined turtle running a jellyfish-hunting business from a cozy submarine. Using a bubble gun, you must chase down electric, mutant, and explosive jellies, then sell your catch at a tiny shop—the faster and rarer the jellyfish, the bigger your rewards. 

You must also salvage ocean-floor scraps using a laser blaster, collecting trash, crystals, and fungi to upgrade tools, your sub, and even your shop. However, although the game claims to have idle mechanics, it requires constant input, which may deter fans of passive play. 

Underwater business experience 

Shelldiver offers a charming underwater adventure, complete with cozy visuals, a lighthearted tone, and a satisfying upgrade loop. While its arcade-style mechanics keep you engaged, the lack of true idle features may not suit those seeking a more passive gameplay experience.
