Hello since I think I was the first one to find this in the new update and I have tested a lot of attempts here since the first one
[SMB1 Brown Ground] why are you here?
[SMB1 Gray & Black Blocks] you want the bullet maze? Well too bad...
[SMB1 Smile Cloud Block] it hasn't been made yet!
[SMB1 Red & Blue Mushroom Blocks] there's nothing left, pls. leave!
[SMB1 Dark Green Wooden Block]
(This is the part where this is how far I got because is a parkcore)
I hope this helps out on the the text if you want to make it you gotta build some speed before jumping.
