I am about 90 minutes of playtime in and to date this is a mixed bag.
The most mixed bit is the save system, which seems to be exclusively based on checkpoints but doesn't tell you when one has been reached. Which has probably contributed 15 minutes of (re)play time to my endeavours, and makes exiting the game a bit hope-and-see.
It also doesn't have the most intuitive interface. What to do is one thing; how to do it is another. I would recommend leaving the hint system on, which will appear top right and will tell you what keys do what, which should make things more manageable. The opening scene with a sailing boat (which of itself is a pretty good buzz) should give you an immediate sense of what I mean. The objective top right will tell you that you need to get the sails down. How you get the game to do your bidding (e.g., pull that rope, wind that winch) is a whole other thing. What keys do what is paramount, so as I said, leave/toggle the hint on.
Having survived my ocean adventure, I have spent my time preparing for a storm to hit. I am Will, a lighthouse keeper, and my first person efforts have involved reading instruments, starting generators and ensuring comms are sound. It looks and sounds good, is voiced, and uses the keyboard to do most things other than interact with the world, which utilises the mouse.
Hotspots appear visually, and things you can interact with 'glow.' Puzzling wise it hasn't been hard to date and having items will cause them to be used if you pick the right place. There seems to be more than one sort of collectible if that is something you enjoy.
I will certainly continue, but am hoping the save game system will be patched.
