Hello MonkeyHQ,
Unfortunately, I will be
Rejecting your map.
The theme isn't very original, as the theme of minecraft items has been done many times. Please refer to the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The build isn't great, as it's pixel art. Unfortunately, maps that have pixel art as their main build are no longer accepted. I understand due to the nature of the theme it would be difficult to prevent having pixel art as the build, but in the future try to make sure your build is more 3 dimensional, with more shape and depth.
The parkour is well varied, you used a great variety of blocks and items to create original and enjoyable jumps, however, a couple of the jumps you built are impossible in 1.8.9. Make sure when you build parkour that all jumps are possible using 1.8.9's mechanics.
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.
