Heh, "feature complete"??
It's an open-world survival/crafting/farming/looting game that mashes the developer's own hinky Craftopia (3 years in Early Access and still going) with a Pokemon parody/kitbash coating.
This game wasn't ever made to be "officially released". It was made to pay off right now and, if it works, to keep adding features and shit for as long as the fad runs on (maybe forever, we'll see, but the more successful it does, the more the idea of "feature complete" becomes a pipe dream as it builds for expansion and service.)
It might hit 1.0 some day and lose the Early Access designation (which is sort of a marketing stunt of itself, that s game gets 2 launch days in the press cycle, ) but games like this are never complete.
