In the trailer for Version 5B, I noticed that the pain sprites for Bomb Man and Fire Man used in the Chapter 9 lab cut scene actually face the camera rather than the usual perspective:

However, in the actual game, it's not the case:

I know that the old skin creation tutorial CutmanMike made (http://cutstuff.net/forum/viewtopic.php?f=18&t=475) said that they only made intercardinal rotations for the pain sprites since "this was initially to save time but you can create them all if you like". I also know that V5B featured updated skins for Bomb Man and Fire Man by Dimpsy and FTX. Did they try to add actual cardinal pain sprites before the MM8BDM dev. team removed them for whatever dumb (I assume) reason? Or were they just the original pre-V5B sprites (as given away by how Fire Man's eyelids are portrayed).
