Most games unless it is a sex game shouldn’t have sex in it. My kids play lot of the same games I do and I don’t want them having access to sex in a game.
Most times it adds nothing to a story and is there just a preversion thing.
Not sure of the rip off part but when I saw the game play my first thought was of CupHead. Nothing wrong with that. I like the graphics. Wonder if it is just as hard to play?
