Out of curiosity, what kind of perks would people like to see. Aside from damage/stat boosts.
Also does anyone actually think the sleep status effect is an actual threat? Not counting during Sofia 'fight'.
Excellent question - perks are a great base that could use more attention.
I would LOVE some kind of "comeback kid" type perk (PLS GOD don't miss the opportunity for a comeback->cumback joke) where if you would lose your last spirit you get it back and some short duration buff to try to pull a last minute win out of your ass - basically a fancy +1 spirit perk, but the flavor of having it kick in at the end rather than the start would be nice. Could be a partial heal and an attack buff or something?
Enemies get a fair number of on-cum perks as well, would be nice to have on-cum or on-orgasm player perks as well. Say when an enemy orgasms she gets a sensitivity debuff (cuz holy fuck after one o them babies there's some sensitivity going down) to exploit, could be useful for multi-Spirit enemies like kunoichi. Or when you cum, you get a temporary regen perk or attack buff, or inflict an aphrodisiac to the enemy. Hell, speaking of status effects on ejaculation, this might be a good way to bring back the old "stun on cum" thing, just limiting it to boss succubi and similar major enemies.
And why isn't there a heal over time effect? We have the equivalent of a damage over time effect in Aphrodasaics, there should totally be the inverse of that. Both for skills and perks.
It'd be interesting if there were mixed-bag perks as well, though this may be getting too overwrought, complex, or not-totally-positive for your tastes. Say a perk that inflicts you with an aphrodasaic effect AND increases attack for x turns after its conditions are met. Ditto for skills. I'd love the ability to say, have an attack buff that also inflicts aphrodisiac on you, or damages enemies and heals you (pseudo lifesteal).
Some perks for various sex types might not hurt... enemies get Undeniable Pleasure and player gets Pacing for recoil, but maybe perks that benefit specific playstyles, could be enemy debuffs like "increases enemy's Sex vulnerability" or increasing the power of thrusting moves, to make that playstyle a little less inherently risky, or a small discount on magic moves, or a buff to Seduction type moves in general or more specifically moves where you touch the enemy... etc etc. If you wanted to go full power you could even do stuff like "duplicates all thrusting damage at 50% power" or "enemy loses 2 spirit if orgasms through touch skills" though playstyle-defining perks like that would have to be unlocked much later, like how CoC required 60+ in a stat for its best moves and several prerequisites.
I can see how that could 'enforce' playstyles rather letting players freely do everything within their stat type, which may or may not be a bad thing depending on your playstyle, personally I generally like having more defined approaches to combat so I can better envision the scene and characters (ex. 'my character is a horny dumbass who thinks sticking his dick in a succubus is a good idea' or 'smooth talker with magic fingers', works both ways when I'm self inserting as the female one). But it would definitely be something that would have to be carefully balanced regardless.
