No, and unfortunately never will.
Well, as it was already mentioned before:
One of the characters was a child, even tho obviously she didn't have scenes with her, nor did she ever intend to. Steam chose to ignore the details.
In addition, the original incorrectly assigned tags to the game didn't help the situation.
These are mistakes of the past, nothing can be done now, but to remember this experience and do everything correctly in the future.
