Well I decided to postpone my hiatus to complete 7-20x, but only by slipping between the saws that fall then taking my sweet ass time for the remainder of the level. Here is vid

That puts me at an even 300 levels beaten.
Now for a little beef on Team Meat.
5-3x, 5-15x, and 5-19x are the only ones I have left for rapture, but I refuse to do them for these reasons
5-3x - The repulsors are stupid. My patience with them is growing extremely thin.
5-15x - This level is broken as all get out. There is a section where you have to through a narrow space with one of those leeches crawling on the ceiling. Well every other time you die he will be on the ground, rendering your path impossible. You either die from the onslaught behind you, or die from him.

5-19x - Team meat you guys put the timer on top of a freaking buzz saw you fools. Actually this one I have the best chance of beating but I really don't have the patience at the moment.
Oh and I have encountered the warp zone glitch that Kal speaks of a couple of times. Particularly the one for Rapture dark world.
