Hello <3,
Unfortunately I'll be giving this a -1. The theme is unoriginal, as there are already several maps related to space, spaceships, star wars, etc. The build is good, although it appears to be a bit messy; make sure you clean it up a bit. For the parkour; I see some floating jumps, which is a bit of a negative (jumps that aren't attatched to the map). The parkour could also use more variation, but I believe it may fit the hard difficulty due to length.
I wish you the best of luck! <3
