Hey! I'm going to be giving this map a +/-1. After playing it through, I had a fun time doing the parkour. I don't, however, think it't very aesthetically pleasing at times, and there is a few issues throughout the map. For instance, it can be very hard to know where to go at times. I was very confused on where to go on the snow biome part of the map, as well as the part before jumping into the pond on the desert map. This can be a big issue, as definitely will want to know where to go during parkour. Other than this, there is an exploit on the desert parkour, which I'm sure you're aware of (as you left signs saying not to use it), allowing the player to skip a portion of the map. Besides functionality, I do believe that the map has a very ideal and defined theme and is designed very well, but I do think it could use some work. Overall, I liked your map, but, once again, it could use lots of work.
Cheers,
