I maed a game with z0mb1es!!!!!!111111 or whatever it was called. Best one dollar dual stick shooter. http://www.youtube.com/watch?v=Lz-TQcdXDJU The music is amazing! How do you embed a youtube video?
And I completely agree with that game. It's ridiculously fun, only a buck, and could work extremely well on the iPhone. The only two others I can think of that I'd like to see are Dishwasher: Dead Samurai and Castlevania: Symphony of the Night if you want to count that.
I dunno if it's just me, but I'm thinking since these games look so great... leave 'em where they are. Don't risk their reputation with ugly, badly controlled ports, invent new games for the iPhone built from the ground up.
