Ok, that's fair, but there already is a bit of variety, from the girls' chest area all the way to their proportions and age ranges, and the game's far from being completed, which means one or a few other female characters might be introduced until the story reaches its conclusion.
Stick around, keep playing the game, and see if you like how things unfold and develop in the next few updates, and only then decide if it's worth still playing it till the end or not, cuz so far, the dev does a pretty good job with the story and the characters, IMO.
I'm not big on the virgin LI porn trope, got nothing against it either, but the romance with Ember is so far so sweet and wholesome you might wanna reconsider giving her too much of a 'past' in order to avoid risking to potentially upset some of the fans of this type of romance.
To be honest, her having one or two exes before the MC shouldn't be a problem for most Ember fans, but who knows ?? Ppl already started complaining about certain more or less important things, treating this seemingly trivial topic with caution would be a smarter decision that benefits both you and the fans, is all I'm saying.
And Anaru seems like a sweet girl and great LI material. Already looking forward to clapping those sweet cheeks of hers, and I sincerely hope there's options for threeomes and at least one throuple ending.
The only thing that's not clear to me about this update was that dream scene choice at the end of it... is it supposed to be some sorta teaser for what the player should expect to get from each girl personality-wise or just harmless fap material ??
