This mode is officially BB+ now. Since it's beta testing, here are the bugs I found
1 - Mrs.pomp can give you class work through walls now.
2 - when you use the grappling hook on floors 2 and 3, you just die.
3 - The game has gotten very laggy.
4 - The "GRAND OPENING" doesn't open. I don't know if that's intentional.
5 - I also don't know if this is intentional, but the dirty chalk eraser doesn't work.
6 - When you use the legendary apple, your game just breaks. (Android)
7 - When you get the 4th exit in birthday bash, the game malfunctions.
On the bright side, some things that were previously broken, (some soundtracks and beans), work perfectly fine now.
Other than these (And the intentional portal poster), it's working perfectly and it's basically a legal BB+. Great job!
