Thanks for giving it a whirl! Yeah, this prototype is just the cooking board. There's nothing more to it than putting ingredients together and seeing if something was produced.
I'll try changing the Discard button so that it looks more like a garbage bin (and opens when an item is held), rather than look like it needs to be clicked. Maybe I can put some tool-tips on the unused portions of the cutting board. There's probably a lot I can do with that side of the screen to make it look more natural/part of the counter-top rather than just UI. Changing how the image syncs sounds like a good idea.
Thanks again!
