Hello Chclo,
Unfortunately, I will be Rejecting your map.
The theme is original, it probably isn't the most appropriate theme to have as a parkour map, but there aren't any maps like it.
The parkour is good. You used the different styles of blocks to create many different types of jumps instead of making them all similar and repetitive, which is good.
Most of the parkour is floating. Try to implement the parkour into the build more rather than just having all the jumps floating over the void. Having an excessive number of floating jumps can make your map look quite messy.
The length and difficulty are good for a medium map.
Thanks for submitting your map! I hope to see more maps from you in the future.
