Hello Shaclebolt, Destroyer625 & tommturner,
Unfortunately, I will be Rejecting your map.
The theme is somewhat original, there are a few maps with a similar theme, but none exactly like this which is good. The build is really good, it's detailed and has been built very well.
The parkour has some variety, but does feel quite repetitive in places. Try to mix up your jumps a bit more, as well as experimenting with different ways of using different blocks, to make more original and enjoyable jumps.
I like how the parkour is incorporated into the build, but some parts were pretty unclear and confusing, some parts were also impossible due to the placement of the jumps, make sure to test your map in 1.8.9 before submitting to make sure every jump is possible.
The difficulty is good for a medium/hard map, but it is a bit long for a hard map, try to keep it between 60-75 jumps.
Thanks for submitting your map! I hope to see more maps from you in the future.
