Umihara Kawase was a Super Famicom platformer similar to Bionic Commando, but with a young girl in the place of the beefy military dude, and a heavier emphasis on self-contained, small levels, technical grappling, and ... fish. We adore the game.
Unfortunately, if this is true, we're unlikely to adore the result. Umihara Kawase was recently released in Japan on the PSP (a US release is planned as well), and it's a mess. Basically, the rope doesn't work right at all, failing to hook when it's supposed to, swing the way it's supposed to, or let go when it's supposed to. And if the PSP port (of the PlayStation version of the Super Famicom game) was so lazily and poorly made, what chance does the DS version have? Not to mention that the DS release is in extra danger of touch screen controls.
