Of course there is no gravity modifier in the game, but we can be fooled into thinking we walk on a ceiling. What you need would be an exact copy of a level upside down, where you are teleported to. Now I don't know if this is possible but to make it look convincing you need the following:

- ceiling tiles become floor tiles and visa versa
- upside down torches and shadows
- previously dropped items sticking to the ceiling
- upside down toggled gates and levers
- upside closed doors that are opened vertical now open in opposite direction

Would this be able and rendered properly? I guess monsters upside down attacking would be impossible?

these are all trivial, models support offset and rotation

however, changing gravity and vertical collision handling is almost certainly impossible

for the first point, no problem: but if you do a multiple ceilings, that can be a problem. It don't work for me.
here you have both normal and "inversed" way for the door and levers and torchs, I suppose it is possible.
for the item dropped on the ceiling... well, I can't say it's impossible, as their is always someone who makes miracles
but it seems impossible

Your marble stone tileset looks very cool, bongobeet.

Thanks! I finally followed your advice, and keep only the white marble floor. I have tried a mix with the marble floor and a golden plate, but... that don't look very nice.
