Hey DreamBoyHalo,
Sorry to tell you that your map has been rejected.
Despite we got a lot of minecraft related maps, the theme is still original, since we don't have maps about Dream yet.
The build is not really good, it's quite plain and simple, and the block you used for the parkour makes the build a bit messy.
The parkour is also not really good, it's quite repetitive in my opinion (there is a lot of normal block jumps), the last part is also way harder than the rest, please try using different blocks for your parkour (like soul sand, iron bars, heads etc) through your map, and not only at some spots.
To the other players here, please no need to dislike him so much for not following the format nicely, at the moment I know where the map is, it's enough for me.
Thanks for submitting your map, would be good to see more maps from you !
