@MOKKA I did find one thing out. On my rush to get to the credits again to screenshot each enemy and boss and get the proper names of each, I went through in Tourism mode, and in the last levels (I think the redder, more ruined version before you get to the Administrator), several Karl Von Cowards appear, which is awkward to deal with if you don't also have damage dealt increased since you only have a Level 1 gun for the whole run.
