Oh, I think it's easy if you beat the original game before.
Also fun fact, I was inspired by that creator to make this mod.

Uhm.. I have died like 80 times in BB Deluxe, in my opinion this game you made is easier.
What I mean is, here's the difference: in BB Deluxe, Baldi's slap speed is normal, but the speed when he smacks his ruler I believe is cranked by 3, so when he smacks, he gets 3 times closer to the player, making it hard.
In BBTUD (the ultra decompile), baldi has normal slap speed.
