I like the concept a lot, and its fun to play. I did notice a few points that I think could be improved. Maybe I missed it, but I can't seem to find an explanation of the controls anywhere. They're simple, so its not that hard to figure out, but I think putting them on the project page might make it easier for players to understand right away.
One other thing is the fact the icons are pretty small. I heard Godot has issues with window sizing, so it's probably not your fault, but I think adding a full screen or making the sprites bigger would be abig improvement. Right now I have to get really close to the screen to tell the difference between the milkshake and iced choclolate sprites.
Overall, I like the art and concept! With a bit of polish added, it could make a great game. Nice job (^~^)
