The game won't start up for me running on a Windows 7 machine. I keep getting an error message no matter which exe I use stating that it's "not a valid win32 application".
Might be related to https://github.com/renpy/renpy/issues/2639 which is a person reporting the same error and isolated it to how renpy includes the icon for the exe. Not something a user can fix simply but might be useful to MonsterBox.
