Coma likely doesn't sound like the most engaging ludological venture, you must take a few minutes to check out Thomas Brush's beautiful little browser-based platformer. It's short and sweet, featuring hand-drawn graphics, a lovely soundtrack and a plotline that's absolutely pregnant with artistic ambiguity.
Though that last sentence was also pregnant with pretentiousness, Coma is not. It's just a pretty, simple game, and it's free to play on Newgrounds right now. If you've got a half-hour to kill, we strongly advise you go check it out.
