I played the game for the first 5 chapters and I can say that it feels completely new, it does not play at all like other game.
The production value is amazing, the game is beautiful, fast, with a lot of things going on the screen. It is so action packed that you have a hard time following the dialog bewteen Pit and Palutena.
The air gameplay is amazing for the eyes, with the speed and the reverse of views, it is really beautiful. The gameplay is simplier as you can move Pit on the screen but the bigger trajectory is automatically directed. On the ground, you will need to get used to the controls, as you move the camera and the shoot target with the touchscreen. I took some times to get used to that, but after that, it is quite smooth and works perfectly for the shoot.
The camera is still a bit of a mess sometimes so the platform phase I encoutered was not really in the best condition, but it was short.
The non stop action, the dialogs, the fly, the ground, the boss, the weapons, the amazing production, all of that jump right on your eyes when you play the game for the first two hours.
I tried the multiplayer in light vs dark team, it was a bit confuse for me, but it was when I had not mastered the controls. Anyway, the game is totally different from what you will find elsewhere and is completely refreshing.
