I applaud this game for being very good and very hot. There's just one minor problem I have. Everyone's problems get solved too fast. Lex is a tsundere until she's not, Alaina has mommy issues until she just doesn't, even the gladiator girl flips from being actively hostile to lovey in like 2 scenes. Maybe slow down the character progression a bit so it feels more natural
It would be annoying for a girl you saved to continue being difficult. The mommy issues wouldnt have really been mommy issues if they just took the time to talk about their problems. And Rin is from Serenity and thats how shes always been go play Serenity 1 and 2 first. Theres nothing wrong with how this story and characters progressed.
