Unfortunately I will be Rejecting this map.
The theme is original however the build isn't very attractive, it's hard to tell what you're trying to create as it just looks like a big box.
The parkour didn't have much variation, as you mainly used single blocks, ladders and vines. I would recommend experimenting with a wider variety of blocks and items when creating jumps to see what you can come up with.
It was possibly too long for a medium, the length isn't really a huge issue though, the difficulty was a little too easy for a medium in my opinion.
I also found the parkour confusing at times, I would suggest adding more signs or colored carpet to make it easier to see where to go.
Thanks for submitting your map! I hope to see more maps from you in the future.
