I've been playing J.J. and Jeff lately on my Turbo Express and I have came across a part in the game I was having trouble with before. At level 6-4b (the "b" represents the second part of the stage, of course), there is a part with three platforms hovering over emptiness and at the end of the third platform, there is a tall brick wall that is too high to jump over. I've tried kicking some of the bricks and one of them shakes the screen as if something was triggered, but I didn't notice anything. I'm thinking what I have to do is kick in the air somewhere above the platform for a piece of ledge to appear like earlier in the level, but I posted this thread here incase my plan backfires! Any help would be greatly appreciated!
