Hey thanks for the comment! Yeah, this story arc is very linear, serving as a prologue to the rest of the series. Season 2 will have more interactivity to it, as you'll get to choose which girls you spend time with.
I'm working on SFW mode, which will skip all the lewd scenes so the game can be played and streamed on YouTube and Twitch. I'm also working on going through and making all encounters optional so you're not forced into being intimate with a girl you don't like/ seeing content you don't like.
Cecilia's story is upsetting because it makes sense for the story overall. This isn't your typical AVN lol. I'm an author first, a game designer second, and I like a lot of emotional weight in my stories. But the bright side is, in Season 2, you as the player will decide her fate.
