Compelling but logical puzzles - it's hard to pitch this difficulty level right, but this game does a good job of it. A tight script. Nice graphics. A game structure that ably makes use of the "non-real-time countdown" dynamic that worked so well in the other games.
Any complaints? Lack of character development and a degree of predictability in the plot, and the flashing graphics were a distraction when attempting to read the data pad. Would have liked a wider variety of endings as in the previous games - there was opportunity for this, you've got access to a lab and 3D printing machine that can make loads of stuff, it might have been possible to find another way to destroy the crystal, or at least get the life-support working for long enough that you can communicate first-hand with the rescue ship before they dock. But I liked everything else about it and it deserves 5/5 and all the acclaim it has been getting.
This review may seem unduly negative but
