Heya Mythic!
Just going to be giving my opinion here;
keep in mind that I am not a map judge.
The BUILD fits the theme well, however just as a personal opinion from myself, would be to colour the planets through the use of shading, try to incorporate other blocks into the palette you've used on the planets to do this.
The THEME of your map is unoriginal as we already have a ton of house-themed maps on Manacube. When coming up with a theme I'd advise you to check over this document here:
Maps List - this shows all the accepted maps on ManaCube to date, with their themes to allow you to see if a theme is already on the server.
The PARKOUR matches the difficulty and length of easy, good work on this! One thing to mention, try to keep block variation consistent throughout and don't clump it together. I'd recommend you check this document here:
Jump Variation - this will allow you to grasp a better understanding of what I mean by jump/block variation. Navigation is good and the checkpoint spacing is wonderful, great job on these!
Other than this, I have no further tips on your map. Great work and I hope to see more submissions from you soon!
Cheers!
