That‘s hard to gauge since I haven‘t played Blasphemous or Mandragora and there certainly is some platforming but I can‘t say if it‘s to an extent you‘d tolerate or not. I personally haven‘t broken a sweat so far, it‘s only been some jumping over gaps and the odd breaking platform (essentially platforming on a mild timer) nothing precise if that helps?

I‘d say you have to do some mild platforming somewhat frequently though, at least in the parts I‘ve been.

It’s been nothing like Hollow Knight in that regard, I can promise that much.
