What matters most is your storytelling. If you've got an interesting story and characters, then you'll find readers who will want to binge read it. Personally, 200k words for a webnovel might turn me away. I'd read a few chapters and probably abandon it unless something really hooked me in. What's your genre? I know fantasy can reach 100k and up, but 200k is quite a lot.
But I've seen some novels on here with 200+ episodes that do fairly well. It just depends on what you feel is best for your story. Nobody else can decide that but you. I would say keep your episodes as short as you can tho.
I had to adjust my chapter sizes when I first started publishing here because I had mine between 2k-4k words each. I trimmed them down to 500-1,700ish (somewhere in that range) because that's how I was able to cut the scenes best. I've only ever finished two novels that I'm taking seriously at the moment and am still currently working on edits for both. One ended with 97k and the other fell short at 69k. My first drafts always tend to be shorter.
I add more as I edit.
