Hey there! Very interesting project. This game have a great potential. Can i share my thoughts?
a) I don't know what the models you use for female characters (something by Illusion i think), but not every CG working right with nipples color. Like "barmaid events" or "park event", CGs use color and size for nipples what skin have by default. I hope you working on that.
b) I hope you add many random events with strangers on street, jobs, school etc.
c) I really hope you add many events for landlord (like gangbang party with his "friends" or force prostitution, or something)
d) Sister needs many events too! (May be she need to be a pure lesbian for pure yuri content? Dom-sister i think. And many her events must be are closed for whore MC? Like "be are dirty for her only" or she can be are very competitive for MC attention.)
e) May be need to add diagram for MC like: Homo/Hetero, Pure/Whore, Dom/Sub, etc. I think male and female origins are a good begin for starting parameter "girls/guys MC interest".
f) May be clothes needs are parameters what we can see in diary and description, like:
+7 elegant/ordinary/sport/school/whore.
g) I really-really hope are you don't add too much NPC-NPC sex scenes in which MC just stands/sits/lies/jumps/etc and looks.
P.S.: I hope you add sizes for MC bust and butt (hmm... 3 enough i think? Like small/medium/big. Can be changed by three types of workouts, for example or/and operation for freeze result, after that, the "fitness" parameter affects only the belly. But looking at "park animated CG", i think thats impossible or hard)
P.P.S.: I hope at least one of my thoughts was interesting for your nice project, if not, then just ignore it, obviously, update the game as you intended.
P.P.P.S.: Just forget what i said you about customization before. Developer, just look what the amazing arts you create with ONE model Haven-MC! I really-really think you need to disable so many details for customization and you should use Haven-model only, 3 options need to be changed: tattoos (on/off), pubic hair (on/off) and makeup (well, thats really hard). This will really make your job easier, as well as allow you to create three or four different CGs, instead of one CG with so many options (like now). :3
