Hey fribe, sorry to tell you that your map has been rejected.
The theme is not very unoriginal (there are SO MANY Mario maps now, please try to do a more original theme next time). The build is not great either, it is very plain (even if it does look like the real thing). try to use more blocks in your builds. The parkour is also not very good, it fits the hard difficulty but it's pretty repetitive (mostly ladders and panes, although I like panes try to use lots of different jumps) and it's pretty confusing.
Thanks for submitting, I'd love to see more maps from you!
