I think this is worth playing, but just barely. It's charming, but almost not enough. It still looks good graphically. The story is okay, but the execution and lack of in-game direciton can be frustrating. I despise using guides, but I did for this game a few times simply for time's sake. When looking up guides, I discovered that it was not uncommon to completely miss certain parts of the game. Sometimes this requires players to backtrack, as they may be stuck wondering "I know I'm not the right level for this area, but where do I go?" I got my money's worth though. Plenty of hours sunk into this. Looking forward to see how DOS II expands on this experience.
Surprised I haven't heard more about this game before playing it. After playing it a bit and looking into it further, I read that it's a tribute to Bioshock and System Shock. I can attest to the first, haven't played the latter. It's worth the dollars and time. Spooky, immersive. Encourages staying calm and thinking. Great game so far.
