The game is and will for the forseeable future remain unupdated Unfortunately the game does not function correctly in modern versions of MMF2 so even minor updates would require a huge overhaul. This might happen one day, but no time soon.
That said, this is an old problem that some people have experienced. You can try checking this thread. http://kayin.moe/iwbtg/forums/index.php?topic=366.0 also making sure you try setting things like windows compatibility mode or whatever.
If you donated to download the game and none of this works, please don't hesistate to ask itch for a refund as I can't promise any future support for the game. That said I hope it works and I hope you have fun with it! I'm sorry I can't behelpful.
