I was more confused than offended by the partial nudity and sexualization, but now that I know it's a reference to 80s movies it makes a lot more sense! I would also not trade it away for a game that doesn't include the ending with Alessa and Greta, that ending was pretty funny and it just wouldn't have been the same if it was more SFW.

Hahahaha
Actually, before releasing the game, I considered eliminating that particular scene because I thought that maybe it would be too much. But in the end I decided to leave it, specially since shower scenes like that one were very common in the 80's horror b-films (this shower scene in particular is based on a scene of a movie about an alien monster in an abandoned lab, I think it was from 1987)
