Night Game is being put out by Nicalis, the folks behind the upcoming WiiWare title Cave Story, and like Cave Story it's to be released for WiiWare as well as the PC. The IGF page describes it thusly:
Designed by Nicklas Nygren, Night Game is an action-puzzle game that focuses on providing players with an ambient gameplay experience, challenging the mind with increasingly challenging picturesque worlds. Each level is broken into different areas in which the player must maneuver a ball and using realistic physics to advance through each level. There are no enemies, per se, and no violence in Night Game.It's a good thing we've got that snippet of text because that's pretty much the only thing that has ever been said about the game in the history of the internet, so far as I can tell. Try to picture it, I guess, you might find it exciting.
