Thanks for the feedback! I think a lot of these issues have been fixed in the v0.2 release, so do check it out if you want. Auto-planting is on the feature list and will be implemented later down the line.
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!
