I'd seen this game around for a while, always ignored it because I was getting exhausted of games with ladies with the ginormous boobs. Decided to download and try it today after reading the glowing reviews and praise for it.
My god, I didn't know what I was missing. Easily in my top 3 faps, and I've been around a bit when it comes to h-games. I finished the game with the 'virgin' ending - going back now to throw chastity to the wind and see every scene and animation. The only thing that might be a drawback is the lack of a gallery for ease of viewing, especially since subjugating a floor in the prison means never getting assaulted by the denizens of that floor again... unless the Happy Ending is achieved, anyhow. I don't know, I didn't get that ending.
Anyway, 10/10 game. Decent music, mechanics with a bit more thought than the bog standard RPGM game, and phenomenal English VA for Karryn. In terms of quality, it's up there with the likes of Sailor Splendor, Wings of Rodea, Roundscape Adorevia, and Kozue's Strange Journey.
