Sires, thats one of my favourite bits! I got a positive score (not a great one mind you!!!) I tell you what helped me with the level was too zoom out as far as possible, it helps you get a persepective of the whole level.
The design is really cool, and so is the idea. But the platform whith the first checkpoint is a bad joke. It is basically impossible to reach the next cloud from there, you have to jump on the tip of the vertical line and get a perfect jump. Took me more than 100 tries to get that done, only to fall from the next cloud. Ridiculously hard. That's a big minus there, and I doubt that I will try this level again.
