As far as I can recall, outside poking nodes manually for the pitiful isle exp gain, nada. Even if you technically able to keep gathering nonstop until max level (godplsno), I think you'll still be gated at some levels as they demand some Seafarer Cowries (blue coins) which can only come from selling animal leavings, crops, and workshops. What about those three? Yeah... they are all timegated, too.

Honestly the timegating in that content kinda make me think I'm playing some F2P mobile game with some battlepass weekly XP/Resource limit system lmao.
