Coma is a flash game by Thomas Brush, in which you...well, just wander around a world exploring and helping people out. It's beautiful.
It looks beautiful. It sounds beautiful. And while it's of course limited by the fact it's a flash game with barely any controls, it stretches this about as far those limitations allow.
I've paid for games worse than this. And had it been on the iPhone, would gladly have paid to play this.
