There are two scenes where you can sort of dom Beatrice, both involving her having a cock and being desperate to cum, and the player either milking her dry or teasing her until she begs for an orgasm. Beatrice's scenes are entirely focused around making the player feel feminine by making them "cum like a girl" in various ways, and in almost all instances that kind of forces her into the dominant role in her scenes. I'm really not sure how I could make a route for dominating Beatrice, unless it just doesn't have much to do with feminizing the player, which I wouldn't be terribly interested in. I did have the idea of Beatrice offering sex in more conventional ways for large amounts of silver, mainly as an extra way to use it since I feel the game doesn't have enough things to spend it on, but I don't know when/if I'll get around to that.
As for the bug with audio files, I'll definitely take a look at that. I didn't realize spaces would cause issues on some systems. It may take a while to address though, the tricky bit is that if I change the filename of an audio file, I have to find every instance in the game where that audio file was used, and then change it to use the newly named file, or else it will cause the same issue where it can't read the file, except it would be for all players. And there isn't a great way to search the game for audio files. Also as a side note, do you have any issues with images with spaces in their names? Because there are some of those, and if those are causing issues I'll have to try and fix that too.
As for the purity/depravity system, I do want to add more skills to the skill tree for that, but otherwise I think it's too late in development to add more complexity to the system.
And I'm not sure that there's specifically a lack of art for dom scenes so much as there's a lack of art in general. Finding artists that I can get multiple commissions from per month has proved basically impossible, but I'm hoping to improve that soon.
Thank you for the feedback! I'm happy you've enjoyed the game!
