Hoi vLecheFrita,
Sorry to tell you that your map have been rejected.
The theme is not really original, because there is now 2 chess maps, which looks like a bit your's. The build is fine, would be just better to have less floating jumps. The parkour could be better, it's pretty repetitive and boring, so try to add other blocks in your parkour !
Thanks for submitting your map, would be really good to see more maps from you !
