Perfect, thanks so much for all the detail! To go through that:
1. At the start the idea is you use some of your starting gold to build a couple farm fields, and sell those crops for more gold. It sounds like I might need to find ways to clarify that though.
2. Yeah, my thinking was it's like a cassette player, but I should probably scrap that quirk.
3. I'll fix that for the next build - idk if there's an easy way to programmatically check for that kind of notch, but I'll add some more buffer between the resource panel and the edge of the screen.
4. Ugh, so the good news is I'm pretty sure I've already fixed the building button issue - you have every resource you need, it's a UI problem. The way the built in Godot buttons work, if you move the mouse/finger even a tiny bit, it doesn't count as a click, it counts as a drag. It was a bit of a pain, but there's some code in there now to intercept the drag and manually click the button if the drag was under 4 pixels.
5. Should also be fixed in the next release, but I need to double check.
