Twelve is better, but when picking names it's also important to think about the "Googleability" of that name.
If you type "Twelve" into Google I don't think it'll bring you anywhere close to your game. Even typing something like "Twelve game" might not help.
Of the two, I prefer Twelve, but I figured I'd bring up that it will confuse search engines when people are trying to find out more info on your game.
Before Portal became an internet sensation, it was called Narbacular Drop for precisely this reason. The Digitech students wanted something that would be uniquely associated with their project.
Meanwhile, Portal was as ambiguous of a term as you could get at the time. On the web, a portal was a place that linked you to other places, and "portal game" (or game portal) would be a place that links you to lots of other games just as Newgrounds and AddictingGames did.
But Portal was such a good game that it bought most of the mind-share on the the word.
Now, it's ridiculously hard to be the breakaway success that Portal has been, but I don't think Google-ability is as important as you make it out to be.
