Hi! It can fit buildings as small as 2x4 tiles (including walls). 5x4 tiles if you actually want to fit a door on it.
Does that answer your question? (not sure if I understood correctly)
I assume he just meant visually, i.e. the roof overlay looks too big for the frame of the interior.. but that's a just a matter of perspective! :P
Either way, this pack looks amazing and I had to buy it. I am loving this series and have bought all of your assets, what do you have in mind for the next release?
I made sure the projection is all consistent (although sometimes design / tile efficiency takes preference over that). I think what may be throwing it off for him is that the walls (under layer) are already 'sliced' quite low so that they take up exactly 1 tile without overlap. The roof tiles are not only just adding the roof, but also draw the rest of the wall that has been hidden. Had to do it like this for it to fit with other existing tiles (like the door frames).
As a paying customer and loving fan I would 100% vote for this. Especially if the next tileset is also compatible with this one and the dungeon tileset. There are so many artists on Itch that do a little bit of this and a little bit of that - making it very hard to make a game with say an inside AND an outside (who'd do such a thing?!?!?!).
The other thing that might be nice with these three sets is to draw more objects / enemies, girl characters...
Either way well done. You've done another spectacular job :)
