Very similar to Sexy Heroine 1 with small improvements on almost every aspect of the game.

But playing Sexy Heroine 1 first is recommended for new players, not because the story is the first play is nessesary to understand the story of the second part. More because the story and athmosphere of the second part is pretty weird and the theme for each level is really a random selection of themes not used in Sexy Heroine 1. Kinda interesting design decision in Sexy Heroine 2 .
