Fixed to be more clear, and it works, but isn't the best. If you're falling constantly you'll probably have to repedeatly do /gamemode. It's best to be on survival because this map uses features that only works if you're on survival such as breaking a block with an efficency tool. You can mine it faster with the tool on survival, but in creative you'll break it as if it's a normal block. This certain part is only one section, so it's not a big deal, you can practically be on creative the whole map besides this certain part. :)

Wow, oops, fixed. xD This is my very first thing uploaded. I'm new.
