Ontama is a new rhythm game for the DS. Which is, really, all we needed to know for our hype-generating machine to go into full power. In case you hadn't noticed, we tend to get worked up about the musicgames.
Rather than telling little mini-stories like Elite Beat Agents, Noise Factory's new game seems to be a somewhat more stripped-down, arcade experience, with characters that seem to be limited to describing gameplay. We don't exactly know how the game works, but we can tell that you touch little round creatures (probably the Ontama themselves, since that translates to "sound balls" or "music balls") to send them into icons on the top of the screen; you then hit directions and buttons that correspond to those icons at the right moment, like Parappa the Rapper.
Enjoy the trailer after the break, and see if you can figure out a little bit more of what's going on.
