The game is very good, and makes good use of AI graphics.
I found the English version more immersive than the Italian one. The Italian one sounds cringe, but once translated in English the expressions sound more sexy. This is not a fault of the translation, it's Italian having poor native expressions for porn scenes.
I think that in future Luna should be feminised (at least more make up) or properly rewritten as a femboy or enby.
The triad Sierra, Shego, Luna work very well. I hope to see all three in the same room one day
