Hello Spacecat1203,
Unfortunately, I will be Rejecting your map.
The theme is original, but the build could use some improvements. I would recommend trying to have more focus on the building and having the parkour incorporated into that, rather than having most of it outside. It does look a bit messy and it's hard to tell exactly what the build is.
The parkour is quite repetitive. Try to experiment with different blocks and items, as well as the way you utilize these, to create more original and enjoyable jumps.
The length and difficulty are good for an easy map.
Thanks for submitting your map! I hope to see more maps from you in the future.
