I am testing it now. And will edit my post when finishing it.

Edit: OK I finished it and it`s quite ok. I will say the things I dont like and what I like about the level and story.

Story:
I think the story is quite good but change the gem like cooba said.

Gameplay:
Hmmmm... It`s quite good and a hard at first but gets easy at the second try. I like the obstacles but it isn`t really that hard because If you hit the spikes you can just run until you pass it and only cost 1 health. Those jumping mushrooms are quite fun but seen before. There is a place where you can pick 2 ways good.

OMG GTG finish later!
