Aphrodite, love your game and it's certainly one of my favorites on the site.
I haven't quite played this new version yet as I like to give it a few days for mods to update and bugs to get ironed out. But I look forward to a new run all the same.
I did have a few ideas about possible changes, but they're significant changes.. but I figure why not. At least it may brew some ideas for you.
---Stat System---
Currently it seems to be a 1 - 10 system for Charm/Fitness/Int. I feel like changing it to be a 1 - 100 would align itself with the percentiles that a lot of the games are based on. With it being more granular like this, it would open up more design space. You can have smaller/larger penalties/bonuses. As it is, when you get to higher levels (8-10) it takes a long time of building experience to see your next benefit. I agree with this slow down, but if it's 80-100 then you'd see the benefits of the incremental effect of benefit more frequently. Works both ways as well - you could have a penalty give you -6% instead of it effectively always locked in with minimum of -10%.
---Will System---
This would be a complete replacement of the Action Point system, but used much more frequently and tie in as a primary resource. It would be another 100 point system. It's daily restoration would be impacted by arousal. This would be another reason to manage the arousal. The resource would be tapped to turn down guy's advances, or used to attempt to avoid creampies. Having the action points lost during Orgasm in the current system often made me not concerned with keeping them since they're lost so easily. In a since, the player wants to use their Will to advance their goals but as they get further and further 'reputation' around Work and out on the town - staving off the guys may get taxing. So careful! That is unless you're willing to embrace the lustful lifestyle you've gotten that reputation from in the first place. Someone saving their Will while also getting a strong reputation around town basically would lead right into the 'free use' system.
---Breeder Pill can Orgasm---
Breeder Pill can Orgasm without needing to receive a creampie. Turns into more of a game to get relief and have the Will points to convince them to not fill you up. But Breeder at least comes with an added bonus of that nice auto orgasm when you do get the creampie.
---Addictions---
Addictions will effect how much Will Cost is needed for certain actions. The addiction will fade as you maintain time periods without supporting those bad habits. There can be many here, but starting off with a creampie addiction.
---Exhibition---
On the road map I believe, but expanded here would be great. Might be good to put a femininity requirement on outfits now that there's a lot more outfits. Not wearing panties ideally should have some fun consequences.
---Bimbo---
As reputation builds, the guys should more frequently take advantage and trick the player character.
If you've read through the wall of text, I appreciate it! Hopefully there's some inspiration to be found here for yourself or perhaps some modders. Would love to hear your thoughts. Thanks again!
