Hatch Keep is an idle collection game. It is not Hatchling Post (a daily care routine) and not Familiar's Errands (errand missions): here eggs hatch over time, creatures merge into rarer forms, and completing the collection is the goal. Progress keeps growing while you are away, up to 8 hours, at exactly the rate your creatures earn.
