Most certainly a fan of this update. It's probably a good thing there isn't a Discord, or I could start throwing out ideas.
The voicework isn't bad, though there are some odd choice of lines sometimes. It seems odd for one of the girl's to comment about, "move your hands", when the player's shirt comes off (and they're male). That would fit better with the loss of briefs, potentially.
At the moment, about the biggest letdown in the game, personally, is if you happen to lose. While I can get not just letting the player sit around naked and watch the rest of the game unfold (in the tradition of Valkyrie's Hentai Strip Poker), it's also kind of a shame the entire game just stops. It doesn't feel very 'natural', I guess? I can understand not wanting to perhaps 'reward' defeat, but I think it'd be better if there was something then just the game ending.
I know in my test, there was an interesting moment where the girl's all went through like 3 or 4 voice lines in sequence upon player defeat, which I thought was a nice glitch (I assume). The girls being able to really comment on that was nice, and its sort of a shame it just stopped!
