Hoi NoBlatant and Flue83,
Sorry to tell you that your map have been rejected.
There is not really a theme in my opinion (I can't really count "Walls" as a theme), so please pick a theme next time ! The build is not good, it's pretty empty and unattractive, your map is also way too big, please build something smaller next time ! The parkour could be better, it's really varied, but was confusing sometimes (Mostly because of invisible blocks, please avoid overusing them and if you use them on your parkour, add something on it because we can't see them in survival !), I also think the map is too easy for an insane, but way too long for an expert.
Thanks for submitting your map, would be really good to see more maps from you !
