If you put together your exit like in the picture you are blind anyway!
Thanks for calling me blind
.
Btw. it is far more common mistake that the top is one or two pixels too low, because that is far less visible. I corrected this quite a few times while updating the old Lemmix levels.
Also sometimes just the lower part of the exit is placed as well! When it is placed in a rather narrow area or under a thin piece of terrain.
Please link to examples where one wants to place only the lower part. I see it far more often (e.g. in Colorful Arty's Cheese level) that a top is not placed because it would be completely hidden by terrain, but then the player goes and removes some terrain over the exit and now the topless exit looks extremely ugly.
The
only level that I know of, where topless exits were useful, is
Pieuw's "Utopia". And I am far from convinced that we should keep topless exits, just because of this one single level. (So it is even more useless than invisibility, though far less prone to abusement).
Add a new object to each relevant tileset which is: Exit + top half!
No, no, no, don't clutter the object list any more by adding resp. keeping useless tiles. We want a fast way to select the desired piece, so we want to keep every list of terrain/object pieces as small as possible! Otherwise we only get annoyed by having to scroll though very rarely used tiles.
So my vote goes straight for: Remove the "topless exit", add "exit + top" and (to keep other people happy) keep the decoration piece as an extra piece, where this makes sense (e.g. not for the brick style).
In cases where the exit is already complete without the animated top (e.g. the snow style), I would just leave the objects as they are currently.
EDIT: Added special case for snow style.
