Hello,
I posted this originally on the steam forum. When I open the game, the title screen opens, but my mouse cursor is invisible. There's also a gap in the graphic, a gray square in the lower left. The UI responds to the mouse cursor, as I can move it over the menu options and they light up, and I can click the options as well - but without a visible mouse cursor, it's basically useless.
Here's the log file.
Thanks Leland! I believe I've figured it out; I'll have a fixed version up in the next day or two. :)
