I'll try to fix the problem in an update, windowed mode at the moment doesn't work but it will be fixed.
The game is now updated so the issue should be resolved. If the problem persists please let me know.
I've only just gotten around to trying it, and it still doesn't look like the issue's fixed. I have a Windows 10 computer, if that changes anything, since I know that's caused problems for games in the past. I took a screenshot of what happens when I go into windowed mode to see if that helps you at all. It wouldn't let me take one of what happens when I open the game in fullscreen mode, but for that the only problem is that the main menu is cut off at the bottom and sides of my screen.
Thanks so much for your help, I really appreciate it!
Sorry that didn't work, I will try another fix. Can you please tell me the resolution of the monitor you are using?
Sure, it's 1366x768. Thanks again!
I've updated it again. If it still bugs out could you try clicking the start button anyway and see if the screen is still offset? I cant replicate the bug in testing, so this would help me determine if its an gui bug or something else. Thanks
