I really liked the art and I tried playing it for a while. I was able to grow tomatoes and collect them, but couldn't do anything with them, sell or turn them into ketchup.
I could not replicate this bug, could you tell me if you played full screem and how many farm did you have?
I only had like 2 farms, but had a bunch of tomatoes in my inventory (at least like 40). I was playing in fullscreen.
