Yes. That seems about fair. In all honesty, Caffie was kinda designed with the thought of an asexual in mind. While she understands sexual concepts, she really just doesn't bat an eye of interest on it, but creates a connection with the cosplayers and learns their concepts because of their passion and honesty on why they connected with their respective characters.
This makes it hard for us to conceive Caffie in an actual erotic scene as it seems weird she would be a direct protagonist on them given who she is. Plus, there's the project's worse and best limitation, which is that our artist is really not a fan of having to draw explicit content, while suggestive is mostly fine.
That being said, the reason why it's best it's because it puts a new pressure on us to try and create suggestive scenes that still empower the characters while giving a nice flair of fan-servive, adult and entertaining tone to the game. With the next updates we want to find the footing of where the project is headed, and we want to add some fun moments and scenes of interactions between characters that push the boundaries of the fan-service future while giving more depth to the cosplayers and their characters as well. With some of the ones that we have in mind, I think it'll make quite up for it. 😉
So yes, in the end, I think you're right that the project is more ecchi than it's a full-fledged explicit hentai. However, I still think there's space for a lot of things within it and personally I've been thinking of the motto of the game being "an aphrodisiac in the format of the game". It might not be enough to make you go over the line, but it should be enough to make you want it. Here's hoping we can go there.
If anything else crosses your mind do let us know! I really appreciate feedback conversations like this as it gets the gears working. Cheers! 🐳
