I had enough gold: I could buy 10, I couldn't buy 5. But I had a problem of clicks not always triggering - it may have been something like that.
Yeah, that might be it. There is a small issue that seems inherent due to how the game actually works in the browser, making it necessary to "deselect" a prior element you interacted with before the next click will register. I'm thinking about how to solve it, but nothing for now. Btw, if you ever have a chance, please check out the new systems and mushrooms. I'd love your feedback on the updates!
