Dropped $15 in support, I like what you're doing and I hope you keep it up.
Dunno if this ever came up or not, but have you considered any game over events? You did a great job villainizing the newest stage boss, both in dialogue and with that evil smirk you gave her during the H animations. I see there is some nice victory CG on the way, but it'd be pretty cool to see an event when the tables are turned and Tia falls to Sonia and her thugs instead, even if it was just using existing animations plus some dialogue to complete the situation.
Some evil smack talk out of Sonia while she's dominating, some crying out of Tia while she's being raped and humiliated. Something similar towards the beginning of the prologue level would be cool too, seeing Tia get raped along with the rest of the villagers and carted off.
Anyway, just my two cents. Keep up the good work, I look forward to this project.
