Hello Zyphxon_YT,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there are many space/planet themed maps. I would recommend checking the document linked in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The build is accurate to the theme, but it does feel a little plain in terms of block variation, try to use a wider variety of blocks in your build to make it more detailed and appealing to look at.
The parkour has some variety which is good. There are a few jump styles repeated quite often such as neos, but overall parkour variety isn't an issue.
A lot of the parkour is floating. Try to incorporate the parkour into the build more as having an excessive number of jumps floating can make your map look a bit messy.
The difficulty is quite inconsistent, I know you purposely had different areas for different difficulties, but try to stick to one difficulty when building maps.
I would recommend reading over this thread for the submission format, as this makes it easier for map judges to judge your map, as well as making it easier for members of the community to test your map and give feedback

Thanks for submitting your map! I hope to see more maps from you in the future.
