Hey JaShin, i just came to think about this idea
Its about the new feature called difficulty settings
Well, as much as i know, the lower the difficulty is the easier the game gets, so what im saying is maybe the "Surrender" feature can't to be usefull ig for this difficulty feature, because with the Surrender we can easily defeat the boss and enemies.
So, maybe if you add the higher difficulty which is maybe it will be interesting, when Syahata got hit from any enemies it will be more hurt, and the stamina or durability Cmiiw, will be decreased more then the normal one, and when Syahata got caught and got raped, during the fcking animation will give some poison damage or continuously damage while she got fckd
And, maybe you can add the prologue, so we can know, what was happening so the virus got infected into human, and how Syahata got trapped in the female restroom with an infected inside, and maybe just some scene from the outside the school like the city so we know what is going on? (Well, actually i know you already think about this)
Well, i guess that's it from me
