I don't even care much for the "mash spacebar and run to win" default SP levels either. I'm convinced you don't look hard enough, glanced at the uploads section then popped into a public server and find braindead players who may not even want to play (sig below lolol). Most of the good players reside in private servers or JDC.

Play Sir Ementaler's SP levels and some organised matches in camel duels. Or play against Jetbanana who's one of the very few good public players. I know more challenging SP levels, they are just scarce to come by.

And of course there are always those...tests of varying difficulty. Most who start off struggle with them. But that's not really the essence of JJ2, it's mostly learning how to control your rabbit.

...and after that, say how easy everything in JJ2 is. This is all from my years experience.

However if you haven't lost interest just because of the whole "too easy" thing, then nevermind this post.
