Well I'm not saying that's a requirement, however that seems to be the common fix among people who don't get the achievement. Do it one level at a time, and finish the level, don't Save & Quit. Personally, I quit a few times during my playthroughs and still got the achievements, but from the ones who don't seem to get them, playing the levels in one sitting seems to fix the glitch. Glad to be of any help I can. =D
And no, you can't skip the credits. =/
