Nevermind, it was a huge disappointment.
Going for score is a game of playing "what is the playstyle the devs decided was best", not "do your best and know the mechanics". The AI is completely unpredictable, and not in a good way. They just do whatever, and that cripples you on missions that require taking down enemies fast or if you're going for score, because the map is too large and the time lost on traversal is too much. Score-wise, traversal takes too long and tanks your score. Mission-specific, traversal makes more enemies spawn completely away from you.
One mission in particular has planes dropping bombs, and you need to destroy the bombers fast. Thing is, even if you're fast with taking them down, sometimes two bombers spawn really fast, and if both drop bombs on opposite sides of the map (that is large enough that you can't traverse if fast enough), the mission is failed for no fault of your own. And even if you manage to take down both bombs, they'll be dropping two new ones on opposite sides soon after (because they always drop on the opposite side of the last). Mix that with large amount of enemies that can decide either to track you aggressively or just ignore you, and that mission becomes an even greater nightmare.
NG is playable, but NG+ is when these issues creep up so hard you're reseting missions dozens of times, and it starts becoming unplayable.
