Hello, the theme of the map is pretty fun, I hate building reversed things so I'm quite impressed of what you've built, but some part of the house is empty, concretely, so it's a 0 for me for the atractiveness of the build itself.
For the jumps all I see is ladders, some floating jumps, and fences, and ice.. For me, when you speak of r"eversed", I want a jump where at least you can sense the gravity of the game, I don't know maybe some slimeblocks.. And the bookshelves are a good idea for neo's, NdM 1 jumps etc.. So for me, for a HARD parkour there isnt enough different types of jumps : -1.
I've seen many of your parkours before being denied, well try to make *at least* different jumps. You can inspire your ideas from the Net to make it yourself a different type. The build is a part of the jump, but the players want to have fun and tryhard depending of their level on a jump that will impress them. Try to take their place and build what they want to see.
