Exstetra from Unchained Blades developer Furyu turns kisses into power. When Ryoma defeats monsters he absorbs EXS energy. EXS energy can be used to activate special techniques.

He’s the only one who can do this, but EXS energy can be passed down to other characters… with a kiss. Extetra has a kissing mini-game where if you press a button on time your kiss becomes more passionate and you increase the power of the EXS skill.

Exstetra comes out for Nintendo 3DS and PlayStation Vita on November 7.
