Heya Wallet!
Just going to be giving my opinion here; keep in mind that I am not a map judge.
The BUILD counts as 3D pixel art, as
@Luck_voltiaa has stated above. Maps that are 3D pixel art are not accepted on ManaCube anymore. When coming up with a building design try to make it unique and as distinct as possible, ensure that lots of detail and depth are added as well.
The THEME of your map is unoriginal as we already have a large Minecraft blocks map 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 is a lot better than your past map, so you're really improving; however, try to keep that 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. No issues with the parkour at all, other than a few navigation issues, a few more signs would fix this up fairly quickly.
Other than that, I wish you all the best with your submission and future ones!
Best Regards.
