Hello Quakrul,
Unfortunately, I will be Rejecting your map.
The theme isn't original, as there are many maps that are biome/minecraft related. 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 mainly floating islands, it is accurate to the theme though which is good.
The parkour is quite repetitive, you did have a few different jump styles which is good, however, the jumps are grouped quite a bit. What I mean by this, is that you would have a sequence of just normal blocks, then just fences, etc. Try to mix up your jumps a bit more throughout your map, as this will make your map more enjoyable to complete.
There are a lot of floating jumps, in the future, try to incorporate the jumps into the build a bit more, as sometimes having an excessive number of floating jumps can make your map look a bit messy.
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.
