I would like to note that the amount of color themed parkours is a bit ridiculous in my opinion. We have rainbow, blue, green, and red. I personally think that it gets repetitive after a while.
Overall the map has very little contrast, and is extremely similar to green parkour. The lights running up the side, the clay walls, the ladder parkour all remind me a lot of green parkour. While it is a hard parkour, the checkpoints are really close together. The signs wishing people good luck seem a bit condescending, although I am sure they weren't intended that way. Using the blue clay as a background where the lights are is a good idea, but it really only looks good if you are in 1.8.9. In 1.12 the colors are more true to their names, meaning that it looks less purple and more out of place. Also, the purple clay is one of the least appealing colors in the game. To me the map just doesn't seem original, doesn't look the best, and is very similar to maps already in parkour. I'm sorry, but your map has been declined
