Gave this a go, after putting my name it seemed to load for a few minutes (that surprised me, is it supposed to?) BUT once the game loaded proper no issues. Pretty fun so far! (and do I HAVE to send Nim to the manor, she's so adorable!)
Edit to add something: somehow momstergirlhunt.exe disappeared altogether, have to reinstall it. Hoping maybe redownloading and reinstalling it will some the issues before!
