Oh god, richman. I didn't notice what you posted here until today, and couldn't see any notification. I'm really sorry for the late response. But, if you are still interested, I'll try to help.
First - could you (or anyone) provide me with links or ressources to some more soft core japanese pics (particulary sets of pics of same person in same situation/ setting) which suit the content (regarding surrounding/ context). That would help.
First of all, keep in mind that some time has passed, so I barely can't remember the details. For the sources, I just googled something like "japanese sexy gallery" and see what it shows. Here are two I used to search usually:
JPbeauties
JapaneseIdols
JPgravure
I guess you will have to find the name of the models you like and then search for different galleries.
Second: Would you, Rinascere, like that I share with you what I did (will explain in the end) or even work together on it?
Third: Once I made a sufficient progress (which can take months from here), would you be okay if I publish it here on milovana, giving you and figroll credit?
Reading what about your concept reminds me of what I wanted to do with my tease: having a competition at the end while you can travel from there to there doing things, in my case, inside the temple walls during the first part. That, of course, was heavily limited because of the amount of time it takes to develop such a thing. It's not only making the surrounding "world", but also you got to fill it with characters and events to make it feel alive.
About the gameplay (and this is just my personal opinion), I don't think skipping some specific technical forms would fit. I mean, that is like defeating the whole purpose of doing a Technical Forms theme game. Instead, it could just change it to an easier form, for example, or give the player some time to rest between orders, or even changing to different levels of nudity depending on your actions. It would really great to see some others abilities, although the programming part should be hard.
Overall, it looks like the main focus of the game would be the final competition. Some abilities of the librarian phase could be optional, giving the chance to pay the price of stroking at the beginning to have an easier gameplay later on.
I also don't understand how the "energy" mechanic works altogether. Typically, players already have their own "energy" while stroking, that can make them lose the game if they get too aroused. So the "energy" bar ingame should indicate another thing. Perhaps building that energy to use that points later on paying skills, like mana in RPGs? Maybe that was your point and I have not understood properly. In that case, the addition of objects could work too.
At the end it all depends on what is your conceptual vision. If you want to give more importance to the character development, or the gameplay, or whatever. Random/branching events also give a whole new layer of complexity, but you got to develop things that players may never experience.
And finally, about publishing here: please do! I didn't ask permission to figroll to be fair (which I truly regret at this point

) and, obviously, don't own the rights to use any of the images of the tease. It would be very hypocrite of me not letting you publish your creations. As long as people get properly credited, it would just have no sense on limiting ourselves. This way we all win. But keeping that apart, it would make me very happy to see someone expanding the lore!
And sorry again for not answering sooner. Please, if you keep working on the project, I'd be glad to see what's going on!
