Having to replay levels

[veljaaa]

Hello, guys. I just started playing DmC, and I'm new to Devil May Cry games in general. What I've seen in these first 3 levels I played is that there are some areas that are simply unreachable until you unlock a specific ability later on in the game, and then replay the level.
For example, I've seen a red door (the one that can be broken only with a demon weapon) in the first level, or some huge gaps that I couldn't jump in level 2, which I know I would be able to jump over with angel jump I got later on.
Now, I don't really like to play the same levels I just played, even on higher difficulty. At least not for a few years, until I forget the whole game, that is. But, by then, I will probably lose my saves, too.
So, what I want to know is, how much of the game will I be missing out in this way, and at what point in game will I unlock all of these abilities? And by abilities, I don't mean all attacks/combos, I just mean all game mechanics related things, like longer jump, higher jump, etc. So far, I've got a demon axe, angel scythe, demon/angel pulls and a long jump.

You'll unlock all weapons for backtracking after finishing mission 10 or 11 I believe. You'd be missing out on a few secret missions, lost souls, maybe a few items too.
The point is DMC games are meant to be played more than once, for completing these secret missions and getting better ranks etc. , well for me that is at least

Yeah, I get that some people like to replay levels for the score and such, I just never liked repeating what I did just so I can get a bigger number. When I play games, I play them for both the story and the challenge, and when I succeed, I don't really care so much about how well I did, I just know I did it.
But, who knows, maybe I actually play this game again once I finish it. (I've said that for Dishonored, God of War, and countless other titles, but never got to actually doing it). Anyways, thanks for the answer.

Ugh... DMC games are to be replayed 100 times

If it helps, you can just wait until finish your first run of the game and then replay all levels on a higher difficulty since you will keep all your unlocked weapons and skills. That way, you can acquiere all the secrets you missed on your first run while playing it on a harder setting, which adds more of a challenge to it.

I hate having to go around searching for crap anyway, the fact that you can't get it all on your first play through is absolutely stupid, especially since I wasted time on some bit that you can't get through without aquila.
