Is there a game out there about a heroine that travels with a tentacle monster?
Like in art, it's a small monster travelling in her backpack and helps her fight with enemies (like in "Tentacle Training" doujinshi). It could feed on her 'love juices' and grow stronger, slowly and unintentionally corrupting her. There could be a part where she loses her pet and realises how she became depended on it and weak.

I think a game like that have a lot of potential (both in story and mechanics), so I am wondering if this concept was already used in a game.
