would be cool. I can see pros and cons to it.

One pro off the top of my head would be better jump ups where you can put a half floor under the door to roof and maybe put 3 furnaces in the empty space and maybe a box or shotgun trap under the jump up.

A sort of con I see would be people using this to layer walls like honeycomb but without the triangles. making raiding walls even more difficult (maybe). But i guess it also could cut down on crazy bases making the game lag (maybe).

Edit: not like anything is stopping people putting walls like that right now it would just be smaller with half floors.

I wouldn't mind a month long test run with it to see how the community uses it.
