Hello <3,
Unfortunately I'll be giving this a -1. The theme is unoriginal, as there are several maps relating to space, spaceships, etc. The build is good; however, it may be considered messy, but that might be due to the fact that this was built in a small space. Consider using the map maker world next time; there is much more room without having to merge plots. For the parkour: Watch out for floating jumps (jumps that aren't attached to the map). I see some neos, so I believe this might fit the medium difficulty instead of easy. There is some variety in the jumps, but I would consider adding more.
I wish you the best of luck! <3
