Thank you for your feedback! The rotten potatoes are based on the fact that real potatoes are in the Nightshade family.
As for the difficulty, balance has been really difficult post-jam. I really just need to get some more depth into the systems.
I thought about a visual indicator of plants being ready to pick and decided against it to not introduce too much visual clutter. Glowing yellow, or something like that would be a lot less obtrusive though, so that's a good idea.
