Hello Thirstae,
Unfortunately, I will be Rejecting your map.
The theme is original, there aren't any maps related to this and I like the idea.
The build isn't great, as it does look a bit simple and messy with the parkour. In the future, try to create one or two main builds that are relevant, then implement the jumps into that, rather than having a lot of smaller builds, with jumps floating between them.
The parkour is varied. You used a nice variety of blocks and items through your map, making the jumps enjoyable to complete, so well done!
Like I previously mentioned, the parkour feels a bit floaty. Try to avoid having an excessive number of jumps floating over the build and void where possible, as this can sometimes make your map look a bit messy.
The length is good for a hard map, and the difficulty varies from medium to hard.
Thanks for submitting your map! I hope to see more maps from you in the future.
