Hello Marraca_Man,
Unfortunately, I will be
Rejecting your map.
The theme isn't very original, as there are many maps related to biomes. I understand that wasn't entirely your theme, but based off the build, it does look like different biomes. I would recommend referring to the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The parkour has some variety which is nice, however it does feel quite repetitive as you have grouped a lot of your jumps. 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, and experiment with the way you utilise these blocks, to make your map overall more enjoyable to complete.
The difficulty is good for an easy map, and the length is good for a medium map.
Thanks for submitting your map! I hope to see more maps from you in the future.
