The game was written by Greg and Brandon, so yeah, it's canon. Personally, I haven't played the game, but I'd recommend buying it (or at least renting it) to support the Young Justice brand.

Also, all of the comics are canon. They got canned, but just like the show, fans are trying to get DC to continue it.
