I went into this game wearily, as I only liked the original Stasis and hated the sequel, Cayne. But this is hands-down one of the best adventure games I've ever played! Some of the puzzles are a little unintuitive - no moon logic, just a lack of info - but there are hints that pop up after awhile, and there are fewer near the end to match the pace of the story. One caveat - this game is dark. There is one sequence near the end that genuinely made me queasy, and there are a host of disturbing imagery and lore to be found. It was worse than anything a AAA studio will attempt, even Dead Space. If you're at all interested, try it out. It's only $20, and it took me around 12hrs, and I was using the guide to speed through it.
