I like sex scenes as much as anyone but personally I think he's done a great job pacing the game, including having a decent number of early lewd scenes and then leading up to some full sex scenes (most of which are really top notch IMO). I don't mind that Annie and Dahlia haven't fully given it up yet. They'll get there, and have already had some lewd scenes, just haven't fully sealed the deal yet. I assume we'll get some threesomes in the somewhat near future as well based on his previous game and some of the dialog we've seen from the girls in this one already. We already sort of had one if you count voyeurism (the Matt scene).I don't think you get what I'm talking about. I'm asking for more of the scenes to be actual sex scenes, not for the dev to increase the total amount of scenes in the game. I'm sure there will be plenty in the finished product.
I think my only real complaint if I had to nitpick would be that the game is pretty linear. I'd like to see a bit more branching so that choices seem to make more of a difference even if many of those paths re-converge at some point but the story is good as it is anyway.
