One of things I love most in this game is how consensual the sex is. Allied with the amazing gameplay, makes a really nice porn game, where sex is a reward. But, in this context, there is two situations where I think the sex isn't really consensual, at least not for the player.
I have playing the game on hard mode, since I'm replaying the game. I'm not shure if this issues happen on normal mode, but your game is a little easy, and I think that all replay value is on hard mode, so I will report based on hard mode.
I really liked the new debuff of breast expantion. It don't pause the gameplay anymore, and you can continue playing. Since the most of enemys is ranged, and they just fuck you if get in contact, you normally safe to keep going without been bound to fuck someone, but you can if you want. But, in hard mode, a single breast expantion is normally enough to fill up my libido bar to max, and put me to masturbate. This is quite annoying, principally in the Deep Soil, where it's a common mechanic. Sometimes I just want to get past to some area, and I recieve this debuff, and I'm obliged to watch Alicia masturbate or fuck someone, what stop the gameplay, takes time, and dont give me too much desire to explore this area. I understand that it's a debuff, and should have consequences, but I think this way is too much. The worst part is that, once I had recive the hit, there is nothing that I can do, just wait. It's too much punitive, and it's sex been used like a punishment. I think a possible solution is to get the libido bar a little lower when you kill a enemy, in a way that (in hard mode) when you kill two enemys your libido bar still raise, but not enough to make you masturbate. This way, if you're looking for some action or some exploration, you can (and should) continue to kill enemys, and or if you're scare to keep going, you can wait and deal with masturbation mechanic. I think that, this way, it's less punitive, more consensual, give a more fluid gameplay, but it's still a debuff, you still have to be careful to not touch anyone, have to kill enemys fast, but your gameplay just stay playing. Besides, two breast expantion in a row will still put you to masturbate, and you still will have to be careful after take the debuff.
Other issue I have it's the lose clothes mechanic. If you masturbate,even a little, maybe for accident for exemple, you will get naked until the next checkpoint. I think the clothes don't have any function except the estetic one, so you are bounded to just deal with the nudity until you came to next checkpoint or die for nothing. This isn't exatly annoying, but... can be better. I think that when you masturbate, you clothes should just drop on floor, and you could grab it back (with the up-button) or, if you want, you could walk naked. Maybe breast expantion still should bound you to be naked, like already are, but just to masturbate, where you have strip you clothes for your own will, you should be able to just put it back if you want. I think you just have to deal with nudity in a consensual game if you want to. Other game that deal with nudity very well, but in a different way that I have sayed, it's the Xenotake. There, clothes are itens that you find more frequently that checkpoints, and you can have some on stock. In this game, been naked makes you more fragile, so it's a more appropriated mechanic, but I think that in your game you could just drop it and take back if you want.
After these criticism, I should say that I really love this game. Your job it's just great, and it's one of the best porn games I ever played. I'm really anxious for the final version, to play and replay.
