The game, built on Aaaaa(etc.) technology in its prototype form, evokes Rez, involving shooting at different items to create musical sounds. Each musical track is represented by objects of a certain color, and bonuses are awarded by "kissing" buildings of the same color by brushing against them.
You can see footage of the prototype after the break. It's pretty abstract! No release date or platforms have been named, making even the idea of this as a playable product abstract.
