Alright so I'm no expert and I have no right to give advice but I feel like I have to say this, because Techno I'm a huge fan I really want this game I and want you to continue making games. Nymphomania Paradox was the game that finally showed me that there are good porn games out there and it is still one of my all time faves. I literally would not be playing porn games now if not for you.
I've been on the internet since 2005 and have seen countless projects come and go and in my experience biting off more then you can chew, and feature creep are the killers of most small scale game endeavors. It is perhaps presumptuous of me to say this since I am no developer or artist but focus your scope and tone back on the features and additional girls. I kinda was a little nervous when development was first started and monthly updates were announced, imo seems like that could be stressful since ones focus would be strained by problems monthly, translations, and bugfixes every month seem hectic. Perhaps quarterly releases would be better to maintain focus, reduce workload and could provide a better work structure in general. If you wanna add lots of stuff thats fine but plan it out long before hand. Also adding lots of girls is an exponential increase every time one is added. Just by adding the potion seller as a partner you've increased the amount of cg's you have to draw by a lot. What seems like not a big deal can snowball.
So said my piece i and really hope I have not come off as pretentious. Especially since I cant contribute money atm. I know you don't owe me a damn thing I just want the best for the game and especially for my favorite creator.
