Oh, sorry to hear that. Are you certain it wasn't just an issue of not having enough gold? The purchase is working on my local testing copy.
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!
