shurrikhan-so as id like to agree with you on some of these points theres a developer point of view i dont think your thinking of. so the reason POTD has the ability to be random in its floor sets is using an algorithm to make the tiles different. basically it states that select random tile. ensure its connected to another tile. and so on. its very difficult to do a random floor generator. diablo 2 was one of the first games to do one. and it very difficult. but maybe something they could do is an open floor design. where the game selects a random floor tile set. so again as far as floor design you probably need to be a bit more realistic in that area. and keep in mind whats possible. i would refer to elements and floors you've already seen in game so far. that said the only vertical play in game that i can think of is jumpers. geysers that shoot you up or bouncing circles. or teleporters.
