Are you sure it's non functional? I'm pretty sure you just didn't read my controls description....
Or you clicked 3 and it crashed lol
Nevermind, I just didn't press B, and due to the (currently) monotone #2596be backround thought it had crashed. But now I can give actual suggestions, the graphics and animations are great, though I would recommend making the player go into a title screen before entering the main game, as well as having it so that upon pressing the construction buttons, the to-be-built building will switch to the other building that correlates to the button.
