Upon initially joining, I was treated to this once I was fully loaded in.
Now, there are a couple things wrong with this. The first and most basic is that there is no tutorial system, and nothing telling me what to do when I first join. The game also feels like it is not fully loaded in, since there is a big bottom bar that is blank and almost no UI. The game itself also has a lot of spaces that look like they have the sky-box around them, or that there is nothing behind it.
Now, for fixing these problems. The first and easiest one would be to simply change the barrier color to a different one that isn’t so similar to the sky-box, like a green or a red. For the more difficult to fix and also more pressing problem of a tutorial, that is where I would focus all of my energy on. A good tutorial can really make or break the game. You should also redesign some of the UI, specifically the bottom one. I would just remove the empty bar, but you could also add a lot more. I do like the shop UI though, so I think you should keep that. The wheat fields could also be much bigger. Hope this helped, and good luck!
