Thanks for trying out!
As I was doing it for a short game jam and I happened to be busy part of the time, my main problem was to at least finish the main loop (buy seed, plant, extract, sell crop) somehow, which I barely managed to do.
But then - yes, I know it's overwhelming. Tutorial and incremental progression is critically missing. Ideally, it would start with only ~5 lines of boilerplate code that you'll expand yourself.
