Okay i played it for a while, and i found something that made me crash, you can see it at the end of the video.
The screen always do look good thanks to the color palettes, but i think you might need to add a color for some ui stuff, at the beggining there are a lot of informations, little popups moving around, and i had a hard time telling which object i was supposed to click or double click sometimes.
It's weird being able to drag empty squares, and it would be cool to automatically remove the items in the crafting tab once you're out of materials for the craft you were making, maybe let the player quickly remove an item from a crafting tab slot by right clicking it. (maybe something similar is already avaible and i didn't see it)
I think i also got an oak log stuck in an order slot, i couldn't take it out (maybe because i was supposed to give a regular log)
That is the error i got:
