The rare mix of fun game and hot hentai action perfectly balanced. The lewd action is both consistently in the game and is both a pivotal mechanic, a reward for good game play, and a consolation for failure. Good rpg elements allow you to grind out if need be to get you through tough spots. Powers gained have a wide variety that offers interesting combo opportunities. And the boss battles are challenging and rewarding. Especially so since I didnt entirely understand what was going on before the translation came out.
