I'm a little lost on the true meaning of the theme. What - do you have to make a game that looks like something you'd see on a Windows platform? Like those old Solitaire or Minesweeper versions on Windows in the 90s or somethin?

Yes. I would like something that follows that theme, but you can do the newer versions of windows too. I do not care if you follow the theme or not.

I have updated the main page to include the theme.
