Hey CMPumk,
I regret to tell you that your map is being rejected.
The theme is somewhat original, we don't have any invisible parkour concepts like this one. The build is basically just some walls, with the parkour floating inside. Next time, try to make more of a main build, rather than a plain box. If you do this you'll also have the opportunity to implement the parkour within the build better. Because of the barriers, the map was quite confusing at some parts. You also don't really have any block variation for the parkour (you only used normal blocks), making the map less enjoyable to do. Both the difficulty of the jumps and the length of your map fit the medium difficulty nicely, so good job on that!
Thank you for submitting this map, I'd love to see more maps from you!
Have a great day,
Sil
