What can they update that would need that much space? Or was it the kind of update where they did a few bug fixes but then made you download the whole game again? (I’ve already uninstalled it, so I don’t recall how big the entire game was.)
I played through it over a couple of evenings, and my total played time was probably around 6 hours or so. I uninstalled it once I finished because it doesn’t seem like the kind of game I’d be likely to replay, so I can’t look at my save game file for the exact number.
That said, my impressions mostly mirror @forgeforsaken’s. The game was very linear, none of the puzzles were particularly challenging, and dealing with the gunk didn’t feel particularly satisfying. I had all the upgrades well before the end of the game, so there was never really any need to go hunting for materials… that is, I never had to go out of my way or backtrack for anything.
I enjoyed the game well enough for what it was, but I probably wouldn’t have bought it otherwise.
