to move all 8 directions, i.e. the pipes in the sewer section.

remember about that game, going through a door and falling to my

write a patch which simply draws the attributes to screen and erase
them as desired, but the system you mention would be much easier to
set up on a per-room basis. The downside is that having a bitmap
graphic for the block would leave ghosts (though I think it would
look fine as just a solid block).
