In case anyone is still on the fence about paying for a WiiWare version of a freeware game -- although a couple of years
of anticipation have probably killed that -- this Cave Story
video (after the break) shows something pretty appealing: a second playable character. And not just any character, either. Curly Brace is a fan favorite, appearing in the game in a capacity we won't discuss too much to avoid spoilers.
We're checking with Nicalis now to learn more about her inclusion -- whether she's part of the initial download or DLC, and how her presence affects gameplay. Worst case scenario: we find out on Monday when the game comes out.
[Update: Nicalis has confirmed to Joystiq that Curly mode will be included with the initial download!]
