Map13 needs to be reviewed by other players.
If too big, I have plans to delete elevator.
Need to know how bad before the last minute.

No music selected for map13, as I do not have music available on
this computer. I am oblivious to whatever the music is, or if there
is even any music.

I think the imp frame problem is actually a bug in Doom: when sprites are mirrored, the x offset isn't adjusted accordingly, so the imp appears to "jump". It can probably be worked around by increasing the image size so that the body of the imp is in the center of the image.

Maps will need to be heavily play tested in skill 2 through 4. A very few are still ridiculously hard.
