how do I get it in the game?

I really like the themed world building. It is something that is not explored in my levels :)
The difficulty is quite right and fun, but certain parts are annoying, like putting blocks directly over your head on an edge, where you have to jump off from. I got stuck at such a part in the Magma Area. I do not now how this jump should be made, cause you cannot build up any momentum. It's at the bottom right of the area, where you have to move upwards in a pipe.

Other than that I really enjoyed a larger level for a change.
