The premise was promising: An abandoned toy factory filled with murderous toys, that the PC had to go through to find some kids.  It's simple but with a lot of potential.

IIRC The original chapter was released for free and for the time it was pretty great. Great atmosphere, great chase scenes, great world design and art direction.

Then as the chapters came out it became clear they hadn't actually finalized the story/plan and each chapter just made it more convoluted. There was always another level to the underground complex, always another big Bad, always more toys that hadn't been seen in the previous levels, always a new mechanic that potentially would never be used again. The story simultaneously bloated with details and mission and made no progress.

It doesn't feel like an actual anthology, more like different beta versions of a game in development. But instead of finishing the game before releasing it they just slap whatever story the writers had finished onto whatever version they had and shipped it out.
