Four’s Basics: Definitive Edition (New Fours Basics mod)

Learn math with Four! Everything’s (least) favorite algebra teacher! You (David) have been eliminated from BFB and Four has challenged you to collect all 9 of his Books, doing so will allow you to rejoin BFB! Be careful though, Four won’t make this easy for you and will chase you around the school to stop you.

On the way, meet several other contestants like Pencil, Rocky (to be added), Remote, Snowball, Flower, and more! Don’t be afraid to interact with (most of) them! Walk around and enjoy the schoolhouse while you can…
