Since this month's theme is verticality, I'm willing to ask for a horizontal theme - Like one that was back in TMUF in which I DON'T GIVE A GOOD GOD DAMN WHO WON TUTA MADE THE BEST MAP IN THE ENTIRE CONTEST.
Ok, the theme was simple - ALL blocks have to be tied to ground level. All of them. No ground elevations allowed in the layout asides from those that are still at height zero (zero being ground). No towers. I think not even deco was allowed to be over 1 block tall. Bridge blocks are allowed as long as they're tied to the ground, the lower block is at ground level and it's only one block. And so on and so forth.
Now, under these rules, everything else was allowed. Ramps, platforms, garages now on valley. Only restriction was that the blocks were on the ground.
