Thanks for the 'water reminder'.
I used to include them myself but at some point I was worried I might come off as 'too naggy'. It was only much later that I learned that a certain subset of people 'already' view 'anyone' as 'too naggy' who offers even the slightest hint of critique or advice... ;)

There have been more unused files found in the game related to the Tankman as a playable character, but the Daddy Dearest icon could probably just be a placeholder for BF's icon before it was finished. I'm unsure if the devs have any plans for GF's parents to be playable really and I sort of doubt they will be.

Yeah, maybe you are right when it comes to Daddy Dearest since I took a look at the finished character select where BF is in the same place DD's. But I wonder why they put him instead of BF. It would be cool though a campaign as DD and part of me would like to believe it. Maybe an alternative gameplay where he beats BF, who knows.
