Was quite confused for a while. Haven't finished it yet, but found a void, I suppose it's not intentional: (http://i.imgur.com/1vOA1.png)
Also, wouldn't it make more sense to call this a maze level? I've never actually played a level categorized as maze before, but for me this level is one.
EDIT: Couldn't find my way around that level :/
But it was actually feeling good until I started finding some broken stuff, found at least 2 voids (including the one in the spoiler) and 2 wallswims (not counting the wallswims caused by that void). Sorry for not specifying the screens, gotta get some sleep.
