Evoltion

I second LittleShogun recommendation for Yumina the Ethereal. It's quite funny and has a good storyline. Although, you have to play through it multiple times to unlock certain features. I'm sure you start at normal mode, unlock hard mode, and so on. (Correct me if I'm wrong) And harder modes gives you more to the story. Well.. the side story, not the main story. It's kinda hard to explain. Just know that harder modes give you more content.
