Impossible to make multi-story roofs work.

[DreamingVoid]

A is a 2 story building with a 2 story roof - 4 total.
B is an attached 2x2x1 with another level for its roof - the roof at the level of A's 2nd floor.
You are standing on A's second floor, working through an opening to building B.

If you want to have proper wallpaper, the snaps on many roof and inv triangle walls are insufficient. You can't even connect an inverted left/right wall onto its matching left/right wall.

Once a roof is placed on B in one of the 2 squares touching A, walls to fill in A's hole cannot be placed adjacent to them, not even the inverted/gabled walls that are meant to fit inside some openings - you must destroy the roof, build the wall, then rebuild the roof. Absurd!

The bottom-up stability is ridiculous and removes several logical snap locations. You can hang an inv wall down from the side of the roof going INTO the room, but you cannot place it at the top of the roof in the triangle spaced opening on the circumference at the peak - you have to build UP for that to place. Ridiculous - they both have 2 adjoining connections!

Many roof tiles clip badly into interior spaces, further reducing your build options.

Everything about this game just comes up insufficient. This needs another 3-6 months of work.
