Of course, Cave Story was originally a freeware game for PC, so why buy a computer version, beyond the positive feeling of giving Daisuke "Pixel" Amaya some compensation for his delightful game? This version includes the (optional) updated graphics and music from the WiiWare release, as well as a new "Wind Fortress" level designed by Amaya, with promises of more content updates in the future. Wind Fortress is "kind of tough, but features new enemies no one has seen," Nicalis producer Tyrone Rodriguez told Joystiq.
A Steam version for PC will follow soon, the press release notes. And, of course, a fully 3D remake of Cave Story -- completely different from this 2D update -- is due for 3DS in November.
