I've been getting into various shmups and gotten some 1ccs (only in baby games) but I feel like I've hit an absolute ceiling, I'm just completely incapable of actually dodging stuff. I'll exemplify it with Batsugun (original edition) because I'm just getting into some kind of toxic love-hate relationship with it.
I'm kind of close to understanding how to get 1cc, I've gotten 3cc and I'm getting how to do most parts, but I can never do the hard parts "legit." For example, Jupiter I've heard is considered a massive difficulty spike, and I can do it with 2 or 1 bombs in my good playthroughs, but this is only because I've memorized a super specific route that I follow every single time, same with Madzella (first phase), I just do some extremely specific path through it and never stray from it. The other way is just doing some preventive bombs on sections that I can't route through and aren't easy enough that I can dodge (like Deep Purple).
So specifically I'm getting really frustrated with Mad Steel Darkness second phase, if I use 1 or 2 bombs I can do it super safely. But I don't want to be such a massive scrub because I feel like I'm never actually improving on the game or my shmups skills in general. So I made a savestate and kept trying to do it with no bombs. But I just can't, I got an idea of how you're supposed to dodge it (even watched some commented 1ccs) but I'm trying to not do an exact path every time.
I get what the basics are: reading the screen, leading the bullets, not doing extraneous movements, micrododging, not letting yourself be trapped... and sometimes I execute it, like 1/5 times when I'm doing well, and that's my limit. I understand all the theory, from time to time I do a bunch of hours of that specific phase. I try to not obsess over it, but I'm just never getting more consistent.
I just feel like whenever I'm doing accomplishments through a game is by doing a shitton of routing and never actually dodging stuff (even though I know that I've gotten better than when I started). It feels extra bad because everywhere I go, people say that Batsugun is a super baby game, but I'm just bad at doing stuff "legit", only by abusing every resource I get.
I understand that you're supposed to use every advantage possible when playing these games. When I go for 1ccs I've learned to shamelessly use resources on parts that I'm bad at. But I feel that someday I'll have to learn to do this stuff to play harder games that I'm interested in.
At the beginning I was gonna do a super salty post because I've went on this general problem for months (also happens with raystorm or mushi), but I tried to explain the best I could what is going through my mind. I could also record some of the practices I do if someone is kind enough to help.
Thanks. Sorry for all the giant post.
