You're right, all the time we've spent criticizing Oni's work put together would be enough to develop a whole new game or at least a pretty extensive mod. Fact is, we have other (maybe better) things to do, so we're here only to express our opinions and feelings about this game, which usually translates to posting things like "hot chicks, lame game". I think the reason we post here is because we see the missed potential in this game, but we either lack the time or skill to actually make a better game, so we can only vent. You know who has the time and means to do it? Oni, but as you said, he prefers to put one of the worst versions of Squirrel Girl in the game instead. I swear, this man is like Sony with Bloodborne, he's allergic to money. But it's ok, it's not like I'm angry at him or anything, it's his game and for all I (and most people here) care he can do whatever he wants with it. I know this will sound super condescending, but if he likes his games shallow, he's free to ignore any suggestion to make it any deeper, let the man cash in that easy bread.
I'll keep returning out of curiosity, I like (most of) the girls and whenever a new one comes out I'll use console commands to max out her gauges so I can quickly access all the sex options with her. It's not like I'll miss out on anything by doing so...
