The art is bright and fun, but the narrator really makes this game fantastic - narrating every move as you shoot and smash your way through the story.

Beat Hazard [Steam store page]
An interesting mix of music and gaming - enemies generated by songs. Disappointing that they charge extra for multiplayer (DLC - BH Ultra).

Stories: The Path of Destinies [Steam store page]
A choose-your-own-adventure beat em up, with excellent and unpredictable story outcomes, though the combat becomes a bit repetitive after a while.
