This level is very, very broken. There are many little errors that add up. Some walls that should be climbable aren't (for example, the right wall on the first screen- the wall tile on the next screen above is climbable, and it's possible to jump up to it), and some walls that are climbable should not be (for example, the invisible wall on the left side of the screen to the left of the detector). There are multiple voids. I didn't find any wallswims, however, and there aren't many actual SGEs.
The intro and ending cutscenes made no sense at all. I only found the ending by looking in the editor, since it's hidden without even detector hints. I noticed that only one out of four of the tilesets included in the level is actually used, and that there are two identical copies of the info screen in the folder.
