All right, I have now played all six chapters for all four mistresses. It's a fantastic game, but again, the poor grammar REALLY hurts the experience. I can help you with that. Please contact me if you're interested.
And I wish you would have used RenPy or even RPG Maker instead of... whatever you did use. The limited number of save slots is quite frustrating.
Why so little content for the Becky storyline compared to the other three? That's disappointing.
First place I think is Nikki, Becky is a very close second. Or maybe even those two are tied for first. Ivy is third, but still very good. I'm very interested to see where that's going to go. (Prostitution, I'm sure.) The Lauren storyline... well, if you're into that sort of thing. I'm not. Not my fetish. But if that's your thing, then hey, whatever gets your groove on. I don't think I'll be exploring that one any further, though.
The protagonist, "Jason." What a piece of shit. He deserves everything bad that happens to him, and I'm really rooting for absolute misery to befall him. I can't wait to play the rest of the game!
