And it's kinda broken. I recommend folks wait for an update before buying. It has some serious issues right now: controls are barely functional, terrible framerate issues, and the UI needs a few tweaks.
It's working fine for me. Try to close the app if the frame rate gets skippy. Controls are a bit wonky but I can live with it. Fair warning, they have the cutscenes from Silver Star Harmony so the lyrics to the songs are close to the Japanese translation. For those who played the Playstation version, it won't be the same "Wings" and "Luna's Boat Song" you grew up listening to.
