Fantastic Game! These more interactive kinds of sex games are my favorite. REC and "My Dystopian Robot Girlfriend" are Itch's finest. Are you open to suggestions here?
1: Gallery Mode.
A nice image/video folder on the computer for those extra moments. Stuff like the pictures Kaede sends you during the party. Or things like getting LumberJane topless during the run fights and using the Paparazzi ability. Or literally anything involving Syn. Would also be a nice way to replay 1-time scenes like Yuna blowing you in the public bathroom.
2: Even more Kaede!
I must say, I find it really hot that Yuna wakes up during the night and has no problem at all watching you fuck her best friend. Plotwise, are there any plans for her to acknowledge that kind of thing? A bit much, but maybe Kaede should get her own relationship panel in the stats screen. Yuna's suspicion is bad, but maybe Kaede being suspicious should be good, since she's the more outgoing one. Either way, I'd love for the plot to involve things like Kaede also being ok to wake up, Yuna visually being turned on by watching your interactions with her friend, being able to cook for both Yuna and Kaede in the morning, or even a threesome options for the kitchen sex.
Sorry if this is too much, but what can I say? It's a great game and I am invested. =)
