I was a Kickstarter backer, and hated the episodic release so much, I never even started the game, until the Final release was long done.
I wanted no part of the episodic release format present in the game, and I don't mean the Chapters structure, I mean the artificial splitting into 5 "Books", to sell the game in "Episodes".
So I was dismayed to find that still part of the final release, I found the gameplay breaks, and forced restarts extremely annoying.
Also the overly long summarising of the choices I made, when every "important choice" (Not really that important in most cases), was made blatantly obvious, when I was making them.
I also hated the what others chose system, ripped directly from telltale (hate it in their games as well), and the fact I still saw the system, even when I played always offline.
As for the puzzles, a few small trigger points were extremely irritating, the chain ride up the tower, was an example, the entire chain should have shown the hand, not just a small region higher up, above my head.
The worst puzzle was the tidy up the 9 drawings hunt, that one was just annoying, and not fun, or even sensible, for a toddler to have hidden them all, when they supposedly needed tidying away.
That would have been much better if just scattered in the floor, and the putting in order on the walls, part was the only puzzle part.
The story wasn't perfect, and some parts made no sense, Anna's absense after the stabbing for one, but for the most partI enjoyed the story, barring obvious plot holes. and some inconsistancies, between the three games.
It was the way the final edition was still in episode format, with the five summaries, and restarts, that was the worst part.
It should have cut these out, completely, and just started the next chapter, in the completed final game, there were 14 chapters, and a few interludes, which should have been the all that was required.
Having waited so long to make sure the final complete game, with all patching done, was what I played. Seeing the forced joins, still showing the seams, and taking me out of the game, was the most dissapoining part.
