I have unlearned how to be good at 2D Platformers...DKCR very difficult.

I never stopped playing them. Yay me!   However, that happens with anything. I use to be pretty good at playing a few different insturments. Now I am horrible and cant be bothered with it.

P.S. DKCR's is actually decently hard so it is differently not just you.
