Haha, don't worry there are easier stages than that one!
When you start playing this stage is basically an instant game over, but you will have to beat the easier ones first to unlock this one.
After a while you don't even know what you're doing anymore, you're just in some kind of flow state.

If you like the music check out Adhesive Wombat:

Thank you very much, but it's already in the making ;)
I apreciate the offer though!
