I think the reason why the "variants" of the Gargantuars and Imps (that change nothing) are there is because of the paradox feel. Only thing they did right about it...

For Day 12, I think that's a glitch, not something programmed into the level.

Day 17, yeah, found it weird how ALL the other NMT zombies do their jam effect, even though it isn't playing, while Arcade Zombie's machine does nothing.

Highway to the Danger Room, Imp Cannons always appear at the right side of the field, and fire Imps from the 9th column on plankless lanes. Not sure how'd it work if I comes from a portal. Also not sure about GARGANTUARS coming from the portals. If anything, we need the endless zone to tell us which portals are coming so we can be ready for them.
