ÓvÒ/ Hello!There is actually an opening in the fence right next to the boxes that you are able to jump down to the floor below.It's okay if you couldn't find it though, I'll try to make it more noticeable. I'm sorry for the confusion.
Oh, now I see it!! Thank you for the help! :D
qvq/ You're welcome! If I can do anything else for you at all, please let me know!
