Super Methane alternative levels?
 

I've recently finished all levels of Super Methane Brothers. I really enjoyed the game, but now I've done that I don't know where to go next...

Is it possible to play this game with different level sets (and if so how, where could i get them from, etc.), or edit the levels in any way?

I searched this forum and Google, and didn't find anything that helped at all. Thanks for any help.

Thread re-opened since the content of the other one was deleted.

Sine the othe thread is locked, I'll have to write this here...
