That's Dark Void Zero. They released it for DSiWare at the same time that they released Dark Void for 360 and PS3. I've never played Zero but I finished Dark Void on 360 and it's nothing great. The games aren't anything alike though. Zero is actually supposed to be pretty good.
From what I hear, it's pretty good, but I don't have it yet. I think I would prefer it on the DSi, but since I never play it, I haven't bothered. They also have it on Steam (with achievements), but I've been waiting it to go half price or something
