alright.. with the advent of Freeform Dungeons there are a couple things that are noticed right off the bat. the check for edges is two tiles in, and what that means is for every attack you send toward the edge of a screen - boomerang, wand, arrow, even sword beams, if there is an enemy on the edge edge of the screen, they can't be attacked like an overworld screen.
secondly, this is the way dungeons were intended, when you walk to the next screen in adjoining long wall freeform dungeons (there is no door, just a big gap) you KEEP WALKING past the checkpoint of the wall.. 2 or 3 blocks. This is a problem if you have some solid block only 2 blocks past the wall, cause you walk through it, even if its not on the border.. almost applying to above
thanks
