It's not even a rip off. You just took inspiration of Baldi's Basics. Collecting math notebooks is the only thing both games have in common. Baldi's doesn't have multiple levels. You need about 5 minutes to play through Baldi's, while you need at least 15 minutes to beat the math level in AEWVS. Viktor is even scarier than Baldi, because he gets silent while Baldi screams through the entire hall. I could write even more about why your game is A LOT better than Baldi's Basics, but I got homework to do.
