The main issue I have with it is the dilution of content. I'd rather have one well-told fantasy or sci-fi story than two mediocre halves.
In essence, these are two games in one, with a separate MC for each part... They just happen to exchange their memories occasionally.
I mean, it has been story of magic and scifi mixing from the start. Sure the beginning showed magic more prominently, but the scifi side was there obvious in the writing. Personally i find mixing scifi and fantasy interesting, and a rare thing sadly. Sure there's risk of dilution, as you put it, but do remember that this story has barely scratched the surface so far. And yes, some things could have been implemented better, like showing that you and the cyborg are the same. It's not unheard of for someone in a fantasy story to have two bodies that act and function independently. What is the problem here, in my opinion, is that dev didn't show it to us well enough, instead resorting to mostly telling about it to us.
Now will we ever get to see the full potential of this story the dev envisions, only time will tell. And while the story is interesting already, dev should do well with practicing their writing to be able to convey their idea better.
