This map was not very enjoyable to say the least -
Design - It was a basic, flatland parkour map, with the usual floating platforms, etc, etc. Not very interesting to say the least.
Gameplay - This was where this map was lacking. A lot of the jumps felt forced, as in you needed to shove something there, and it makes the map feel more unloved. The Soulsand tunnel with the cobwebs was completely not needed as there was no actual parkour, just you running. You could have made some soulsand jumps, because, shocker, it's possible! The Lava/Water Jumping level felt just plain bad. Most of those jumps actually make you jump into the lava, and this is negated when people just eat the Golden Apples from the beginning for fire resistance. Not only that, but if you have to make a jump that requires jumping into lava, then it's a bad jump.
I get the feeling you didn't test these jumps yourself, which is what you should do. Make sure they are all possible before doing anything.
The level difficulty and design was all over the place. You go from easy, to normal, to hard, back to normal, what?! WHY!? Just use natural progression, easy to hard, not hard to extreme, to babies can do these jumps! And then there's the whole, emerald is level 2, but wood is level 4... THAT MAKES NO LOGICAL SENSE! AT ALL!!!!
My final verdict - This map joins the refuse of other basic parkour maps that have tried and failed to be good in any way. It was unoriginal, any original jumps are so sketchy that I'm sure some aren't possible, at least legit. And for the love of god, DO NOT PUT A 4 BLOCK JUMP IN LEVEL 2!
This may be your first map, but when people write that, they are asking for flames and critisism. I am no different. I do not care whether you've made 5000 maps or this is your first, I judge everyone fairly, and your map, I didn't like.
Also, if you don't change that title, you'll get even more hate. 10,000 downloads, more like 10.
