A sublime ambient feel makes this a game worth getting absorbed into.
This game is hard. And beautiful. And that is exactly how I like my games. Completing it requires a state of mind sublime as the ambient soundtrack.
You will know if this game is for you. It will call out for you. And if you are one of the people this game is made for, it will make an impression in your heart and become one of your top ten games. It certainly did for me.
