I think this is a perfect game to relax with, and I love the concept that you're going for! While the concept is most certainly there, as others have said, the GDD needs some more development. Especially with MMOs, there's a lot of small intricacies in mechanics, and there are a LOT of mechanics. The core gameplay loop has plenty of mechanics not mentioned, and probably needs to be visually reworked, as there's seemingly no starting place.
I'm in love with the concept, and I'm sure when it comes out I'll get sucked in like I did with Animal Crossing New Horizons.
