Netherlands-based handheld gaming studio Engine Software has developed a cool new piece of tech for the DSi: motion sensitivity. To show off this breakthrough, the company has developed a brief demo video of TILT, a kind of Marble Blast Ultra clone where the player guides a ball around the gameworld by tilting the DSi. It's not the first we've heard of this kinda tech, and it won't be the last. Engine Software isn't stopping with just this tech demo, however. The company is currently working on a full DSiWare game that will incorporate this new technology; though it likely won't be a full version of TILT, but rather an entirely new game. Head past the break to check out a brief video showcasing the tech.
