Took me a while to figure out you have to scroll the page and you can only scroll slowly by moving the mouse at the very top or bottom edge.
You have a bug where the upgrades don't become available to purchase once you reach the required cookie amount.
You have to switch upgrade tabs and then they become clickable. I thought that maybe there are some hidden prerequisites, but nope, just a bug.
No idea what to do with farming, bought two seeds, put them in, they seem to grow, then nothing happens.
So it's just a classic cookie clicker, but you need to polish it a bit more.
