As a free minor spin-off of the Silent Hill franchise, The Short Message is quite decent. The game it's visually pretty the most of the time (the third person camera its out of tune). The story is interesting enough to make you complete the game.

In the other hand, the gameplay mechanics are not original at all and there are so many games of this genre better than this game. But as I said at the beginning, this is a free game so I don't think it's fair to demand much more.
