Hi there! Sorry for the issue! Unfortunately, since the deadline has passed, I can't upload a new build to resolve the issue (if you can hear audio, it seems the problem is just that it's opening too large for your display). You can try this one fix:
1. Right click the .exe, make a shortcut for the game
2. Right click the shortcut, go to properties
3. In the 'Shortcut' tab, there should be a 'Run' section. Open that menu and select 'maximized'. This should limit the game to your display.
If it doesn't seem to work, no worries! I appreciate you trying and taking a look at the game!
