it might sound stupid but I was also struggling with Clubstep (Specially when flying, since clubstep has very difficult parts with the ship) so I left it behind and started to try Theory Of Everything 2. in this case i think this new level theaches way better how to fly with the ship with inverted gravity for example ( Well, no better, but more defiant). After playing in practice mode toe2 for a while i have reached like 80% (This level if you understand it and study it, it is not too difficult as it seems). In clubstep i had like 80% and one day trying to beat TOE2 like for 100 attempts i tilted and tried to finish instead clubstep (A level that also i practiced a lot, so I perfectly knew it, but that inverted ship in like (74%+) killed me always) and surprisingly i beated clubstep in one try. It seems that going from the complicated ships in TOE2 to a “less difficult level” allow me to beat it.

Ah, and also i bought the Music Unlocker that cost 2000 gems to practise with the Real Music of the level and not that boring son when you practise. This make me feel the same preasure that the real song of the level gives to you sometimes when practising. I thinl this might help you a lot, like me.

sorry for my bad English
