Not sure if anyone's mentioned it (search brought up nothing), but MachWerx has submitted his 2nd app - & 1st true game - to the apple store on Sunday and it should be out very soon. It's called "Boom Dice
" and can be played by 1-4 players. (There's a game play video on the site but I don't know how to embed it here, please do if you know how.)
What's really cool is that it is one of the launch games using Aurora Feint's new Open Feint
system, which is a "social platform for iPhone" whereby people can talk to others playing the game in real time, post/view global high scores, multiplayer, etc.
Fyi, other games that are apparently featured as using Open Feint are: Pocket God, Radio Flares, Symbolism, and 2079 (which I'm currently loving!)
