I have the same issue as @PhoenixDragon, I play on Android too. Besides that the game works good.
I really like the Artworks of this game a lot, but what I don't like is that Kiara and the Player talk too formly with each other. It's kinda weird to say something like "I must admit youre doing very good" or "I have to admit...", "I gotta say..." that's not what someone should say during sex.
I also have a suggestion: I think the game would feel better with this fantasy setting and all, if Kiara would have more depth as a character than a sex slave, and if the player wouldn't only care about having sex with her or thinking about her. It's actually a little boring when the only conversations are about how deeply they love each other or how they want to have sex the next time, despite the Main Character doesn't have any Idea of what's going on except for a catgirl being his slave.
Anyways, I like the game!
