Finished the content in this version.
Basically, there are archetypes that you need to "upgrade" your family into which will change their character (Which also makes it possible for you to peek on them, or which makes them more open). Currently there is no sexual content with the family (Other than you molesting the elder sis and fucking her throat while she's passed out, but that's pretty much the only one), and you can only bang your neighbor with unfinished animations. You do have a few naked scenes where you are peeping them in the shower.
The grind in this game is real. I think that the grind pretty much increases your play time by tens of times, so basically for like 7-8 family scenes that last for like 20 minutes in total, you gotta grind for more than 4 hours or so to level up characters and to gain access to certain conversation options, etc (To be honest, I can imagine the grind taking more than 8 hours for these scenes, but as I took the easy way out, I can't say for certain).
By the end I just decided to cheat, max out the stats on the women & MC and use those stats to upgrade their archetype. Even while cheating, it took more than 2.5 hours to force me into that predicament. This is a rather complicated system that's far more grindy than it's worth currently. The core gameplay loop isn't too bad, but the content just isn't enough to warrant the grind in any way, there is also an issue of insufficient information. Most people will just spam activities and hope to level up to get access to new skills, etc.
I can imagine there coming a ton of splitting archetypes, ton of options, etc. I would say that the game would be far better than Superpowered, especially on the character models side, and the archetype system is easier to understand as well. Needs a lot more content tho.
