Nice, man the game really does keep looking better and better, anticipation boosted even more.
Jumping a 2x gap eh, was that normal before? I always kept such gaps at 3 or more, but although I never built ramps like that, I did work similar methods into a few POIs I modded for horde night which basically did the same thing. If they managed to get so far along the path made, which rarely happened, they would fall and have to start over. So same principle.
Sounds like you kept them out from underneath, not so hard on 1st horde night. The one time I used that POI was actually in an MP game, it was beyond night 7 and there were 3 of us up there... so tons more Z in total. They clumped up below and were taking out our floor. Good times. At the end of the night we noticed our neighbors still up top and this noob girl one-shot it in the face the nano-second we took the door down. Twas memorable, wish I hadn't had coffee in my mouth when it happened, my poor keyboard.
