That's what pitfall traps are for...max them out, and you nuke 2 sluts at a time. It helps.
EDIT: In addition, tried slimes yet? Get them to level 10, and they dish out 60+ damage to sluts a round. It adds up quick.
Yea I mentioned that in my review. Beyond a certain point, literally all that matters is having
A: Pitfalls
B: Big dick
Both neutralize sluts, the only enemies that actually matter once str is beyond a certain point. Put in a hypno=breasts trap and grope all the other girls and the game is completely trivial, if tedious, even if it throws 30 girls a night at you.
On that note, the questionaire thing he has could do with seperating the girls into how dangerous they are early and later. Witches and lolis are dangerous early. Later nothing is.
A little bit of depth beyond just hypnotizing all you can and then pimp slapping the shit out of trained knights the rest of the night, in the early game, would also go a long way. Not that it's bad, but...
Should be able to do more with the girls you hypno in general. Its weird how, mistress aside, every girl in the game just ceases to exist after 1 encounter with you. Instead of having the mistress fuck everyone but you, you should be able to send the girls you capture to fuck monsters, shop, fuck random men, etc. Like have a bunch of slots you can 'save' girls in, while the rest vanish after one encounter because there's literally no room for them. Could have different classes be better at different tasks.
Then the mistress should actually sleep with you, not everyone but you. Would make a lot more sense than how it works right now.
