Shells and cash
Core resource loop: crabs dig shells, shells convert into cash, and cash buys more crab production.
WikiCrabs and merging
Confirmed mechanic: buy crabs and merge matching crabs into stronger variants.
WikiOffline collection
Shells continue collecting offline, so returning players should claim before planning the next spend.
