@Roxy So this is what happens when you launch the game for the first time with a non-standard controller plugged in.
as a side note, you can't click the 'OK' button. trying to do so takes focus away from the game, which the window is parented to, so it just minimizes both.
This entire thing is probably not something most people would see, but still kinda interesting.
it's a good thing that this is a one time message. I should still be able to play the demo.
