Some suggestions at 10/10:
1. I saw a magic show yesterday, use lockers as magic props, it's about teleport people from one locker to another locker. Maybe consider this in to the game. Use one locker as a exit locker, when the service is done, the girl will leaving by the exit locker, but only one girl can pass at a time, and it also needed to cooldown after used. The purpose is to avoid sudden crowds.
2. About the resist topic again. I really hope to see it in a future version, when they get abducted they really do resist, pull, keep resist before they unable to resist by physically exhausted.
3. Similar to the second point above. "Human voice" needed to improving too, it's too rigid now. They can cry, they can beg for mercy, and of course they can despair, yelling itai / yamete / iya or iku / modo / dameda etc.
At last, a strong suggestion, hopefully this game can be selling in Steam platform. Steam is allow the game with adult content, also selling the game in Steam can be more easier to promote.
