hi, I have found some skips you might want to patch, some are more insignificant than others, so its up to you. I have the intended path in blue and the skip in red.
Build: The build is not very good as it's just a rectangular checkered-patterned box. It's just really boring and uninventive, which leads to a very unattractive product.
Parkour: The PK was definitely hard enough for a medium but it felt way too short, I'd amp up the number of jumps on the map. Furthermore, you should try to include a wider variety of jumps on your map. There were too many fence and ladder jumps, making it a very repetitive experience.
I hope you take these criticisms into consideration when submitting maps in the future, good luck!
