First of all, this game is gorgeous and has some great sound design. A lot of little details everywhere, and the places tell a story. Obduction follows the Myst formula pretty well: You're let lose inside an unknown and mysterious world with no idea of what to do. You explore and come across buttons and levers and seemingly weird contraptions. What do they do? Well, that's for you to figure out, and you will start figuring things out and understand how this and that work. Then you'll build upon that knowledge and get further and try new things. Then you'll remember that one thing you saw over there... maybe this new idea can be used there somehow? You start out knowing nothing and must put in work to figure out what to do yourself, most of the time. Figuring things out on your own is a pretty amazing feeling. But beware that this game is not JUST about figuring things out - it's a lot about patience and commitment as well. Some puzzles require almost silly amounts of it. You'll not fast travel around - you're on foot. You have to leg it from place to place. Sometimes you'll open up shortcuts between places though and avoid some of the long treks around the world.
A roguelike should be difficult, IMHO, but not impossible. You can do great and conserve ammo and health and fail because the game decides you're never going to get more ammo, health or to destroy all the machines you try to repair/use. The game looked great at first glance, but after hours of playing it never felt I was rewarded for being good or punished for doing bad decisions, it just felt random. And the thing is, because of this imbalance, you won't know that the game has decided to starve you (leading to your inevitable demise) until it simply does which can be in many levels and there will be nothing you can do about it. To clarify I'm not saying the game's impossible. What I'm saying is that it can be, from the very start, and you can't do anything about it and it might take an hour or two of playing before you realize this. So you got skills in that particular weapon and you've actually had the luck of finding that sort of weapon? Sucks to be you then, because you're not getting any ammo for it. Trying to make due with that melee weapon of yours? Well, it'll break soon and we will never give you any replacement because random. Out of weapons? Look, a repair machine. It blew up because random. Having fun yet? No. Stay away.
