Beware, there's plenty of things in here I'm sure could be done more elegantly, but I was mostly experimenting.

The reason it works in level 1 is because you can wedge yourself in that transition section and it shoots you straight up and loops it around to level 2. The door glitch offsets your 'real' position by 1 horizontal tile compared to the 'visual' position. Pausing resets your 'real' position to your 'visual' position.
If you can point out any part of those maps where you can wedge yourself in the wall with the door glitch and trace a line straight up without the wall being interrupted that would let you get to level 8 or 3, but nothing jumps out at me.
And he means the purple blocks in the last tank room. You need crusher for those. I don't think it's possible to glitch over there.
