2 things I figured need explaining -
I have a gigantic monitor that let's me play the game in its native 1920 x 1080. If you're having trouble playing it, the submission window is over, so until then I can't fix it. Try enabling full-screen mode. If that still doesn't work, do leave a comment to let me know, though.
Also, yes, that bit about topic buttons in the tutorial is a placeholder graphic :(
