Piggybacking off of what Zapchi said, even when playing fast and only using turnips the top row of farms is enough to not be able to harvest fast enough.
A bug that I noticed was if I accidentally held down the mouse button and dragged down the menu, the menu would disappear. The arrows also don't seem to correspond with the price changes from what I could tell.
Overall very fun but a bit too easy to buy out the competition.
