I already very much adore this game. I am excited to see what it's going to turn into.
Here are some things I noticed:
The sell button doesn't work if I click on the word "Sell" direclty, I have to click around it. Once my Inventory was empty I re-bought some Items, however customers ignored me still as if my Inventory was empty, and then my game crashed. After that I had to re-start completely.
I absolutely love the artstyle, though it still looks very repetitive. In my past games I'd usually add some more plants against the house walls, maybe some barrels, and also some different trees.
This has a lot of potential, good job so far!
