Interesting start. I don't usually look at games this early in development, but the setup seemed heavily inspired by A House in the Rift, which caught my attention, and is not at all a bad place to get inspiration.
This might sound like a weird criticism for a sex game, but it feels a little too heavy on the sex right now. Like, the sex came too fast and feels like there's not much more going on other than sex. The whole house orgy when we've interacted with some of the girls only once before that especially feels out of place, regardless of how fun it is to watch. It's also a little weird seeing the girls proclaiming that MC is such a great guy when they've had all of 1-2 interactions with him. How would they know what he's like that quickly?
The girls feel like they have potential though, and maybe the start can have a very small rework down the line one the game finds its footing. Though the direct reference of Rikki to Rick and Morty also feels a bit too distracting from what story the game has thus far, though by no means a deal breaker, just a strange choice to me. Kat feels like she has the most stand-out personality so far, she's fun. And the orc lady is super beautiful. Last thing, it feels odd that a game that touts having all the fantasy and sci-fi girls we could want starts off with 3/5 human girls. Like, maybe the maid could have been a robot maid, or an adorable shortstack goblin girl, or something else.
I hope this is only seen as constructive criticism. I am very interested in seeing where this project goes. I think it could have a lot of potential.
