The dev introduced his core gameplay loop with this demo, and I think it's pretty good. There are a few flaws that needs to be mentioned though:
1) Trying to lose takes too long. I mean, technically it's actually quite easy to lose, because your HP is your Stamina, and every time you use an attack you use up some Stamina. Although it regenerates over time (I think?), there's only so many enemies you can fight without being in an "oh shit" situation. However, there are only two options "Endure Pleasure" or "Wait Out Pleasure". One of them uses up EN, and your EN hits 0 you lose. But if you have a lot of EN, or you're fresh out of a good night's sleep... yeah it's going to take a while. A loooooooooong while.
2) Realism. Now, I'm fully aware that it's dumb to talk about realism in a H-game that's about sending your best woman alone into a teeming hive of rapists ready to rebel the shit out of your empire, but I just SERIOUSLY have to get it out how ridiculous it is to send your best woman alone into a teeming hive of rapists ready to rebel the shit out of your empire. Like come on, fucking dude didn't even send her enough money to make ends meet. Is he really trying to end the rebellion? Also he went to the prison with his secretary ALONE. Where. Is. Your. Army. Where???
Unless of course, the prince is the final boss...
3) BGM. It's loud, it's noisy, and it gets seriously irritating 5 minutes in. It's like having trumpets being blasted into your ears 24/7, one's that preaching about the might of the empire, an empire who sent a lone woman to deal with a rebellion hive ready to destroy some shit and burn cities. Having some cock sucking sfx put on an eternal loop would be less annoying than what it currently is right now. I wish I was joking.
4) Only 1 female protagonist, for now. Personally, Karryn's body shape is completely ridiculous, and having to suspend my disbelief is acting against my wish to you know, lewd her immediately. Meltys has a bomb tier body too, but her kind of body is actually realistic. I suppose it takes a giant of a woman with even bigger boobs to swing a halberd powerful enough to knock a giant pig like a rag doll, but I wouldn't mind finishing the game, then unlocking other female protagonists in place of Karryn to play as DLC. Seriously, give me someone skinnier.
