Really fun game! I'm incredibly impressed at how you were able to code something like this. More importantly though, I loved your story! Betty and Audrey's relationship being sustained entirely by them both refusing to acknowledge their problems works really well with how each ending shows a different way of them dealing with that problem.
I originally thought the wrinkle was going to be that Betty was actually the real problem, and she was seeing behavior in Audrey that wasn't there. After seeing all the endings, I don't think that's the case anymore, but I do think that Audrey's manipulation is built off of fear and inability to actually discuss anything with her wife, rather than genuine disdain.
My personal favorite ending was the domineering ending, since I think it's better for everyone this way. I wonder if Betty will be able to overcome her love of covert warfare in order to build a better relationship with Cora.
