This game is funny, because I got it and played it quite a bit, took a few days to get used to the controls and then played it to the end sequence. (With the Missile launchers etc.)
Never quite beat that end sequence, now every time I try to go back and play it again I end up getting frustrated and dropping it for a while...
I never get back into the rhythm of it... and I don't have the patience to play that same sequence as many times as it would probably take to make that happen.
Short term this makes me think back on the days of multiple saves, why the hell do all shooters these days only have one save slot? So I can't overlap my game attempts with a harder or easier setting, I HAVE to beat it on this setting or start from scratch... neither of which I want to do...
I also still think the controls aren't reactive enough.
Because it shouldn't take many hours of play to pick up the game flow... I'm sorry but that strikes me as bad game design.
