Some DsiWare (yes we're still doing that) was so good that it couldn't just stay on the handheld. Weirdly enough, Chronos Twins was the one that made it out, but to the equally dead WiiWare.
I say it's strange, because the entire premise of the game is to utilize the Dual Screen feature of a Nintendo DS, which gets kinda butchered on the split screen of a TV. You traverse obstacles semi-simultaneously, shoot enemies and so on. The beefed up graphics looked pretty neat though.
