I watched a trailer of boss battle on www.gametrailers.com and the guy playing almost hit every pegasus rider on the screen ''they move in circle around you on motorcycle.) so if he could almost shoot them all, controls shouldn't be a problem.

And it's not shoulder view anymore.
You can attack in the air.
There's a Double Jump.
More Extra Missions (not with the main story)
Much more interesting, a very hard mode

Much more things that makes the game more fun to play.
The game is, however, very interesting to begin with.
