No, this is an old decompile using Baldi's Basics Classic 1.3.2. And as much as I'd like to, I currently can't decompile Plus, and I don't think there even exists a Plus decompile. The Baldi 1.3.2 mod menu does work on it, however. And I can't simply make a Plus port with that either.
Because there works the random level generator, and with that you are not allowed to pirate its level generator, plus you'd have to add a new mode to do this and doing code - you'll have to code differently and you don't know what to put down.
