Nice concept!
Some personal thoughts:
I didn't realize what was the crafting box, I was initially trying to put things inside the ice box. So maybe make the crafting box stand out more.
R key doesn't work
It is missing visual cues, I tried making water. Took medium glass, but then poured water and nothing changed. So add cues for when I have successfully added an ingredients.
Its a bit buggy at the moment, Serving drinks did nothing.
