My pleasure, I'm looking forward to this game. You had me hooked with the opening.
I downloaded it from this page, so I'm hoping this is the official source.
As for the white screen, it happens when I launch in either windowed or fullscreen. It's about a 50/50 chance each time I launch if it's a white screen.
And for the Save/Load buttons, I never noticed the scroll bar on the side. Maybe a line in the Menu Screen Tutorial page that you can scroll to see all the menu buttons? Or make the scroll bar bigger/more noticeable.
I also noticed in windowed mode it doesn't resize the screen to fit the window. It just cuts off whatever's not in the window, making window mode unusable. Turn 'Stretch Screen' on in the options fixes that.
Of course, I can't recreate the Tutorial crash now that I want it to happen.
Now that I've got the save/load issue sorted, I was finally able to give this game a proper try. And I must say, I am very unhappy I found this game so early in development. Now I have to wait for this masterpiece to be finished before I can lose a weekend or three to it.
