bler144: I quite like the puzzle area/runs, though it seems like there's a meta-challenge of finding the puzzle areas within this big open structure. That part drove me to quitting. Twenty minutes of wandering around trying to find the actual "game" was incredibly annoying.
Or maybe I was just doing it wrong, but there wasn't a whole lot of instruction on where to go once I finished the first dozen or so puzzles.
I don't remember it being confusing. For me it felt quite linear. Stay in the shadows (or at least out of sight of cameras and robots), try to get to new areas (mostly by turning switches or climbing), avoid the deadly traps and reach the exit of each level.
MarkoH01: The game even has a story? I always thought it's stealth puzzles only without much focus on a story or even emotions.
The joke is that there isn't much of a story the whole time. But in the end there is a little twist and the game tells you why you did everything you did (all the climbing, jumping, escaping and dying) and that is really, really sad.
