Controls where hard to understand for me, i still dont think i got it, first time i accidentally clicked and didnt get to read any of the large text, and then didnt know how to get it back, so had to refresh the page, but still didnt recall, i believe this would be improved with less buttons, e.g. you could have one button that cycles through the items you can build, and F to build it, and after you build something, the build menu dissapears, and then you can use F again to interact.. (a 2 button system)
