As with the other games, the interface is sound and we've not had an issue with the mechanics of either logging on or glitches. Inventory is easy to use and everything is intuitive with game play allowing individual exploration/investigation.
Difficult to rate this one - we went from liking some of the puzzles to really disliking some of them - it's a very hit and miss game with some odd rationale behind the dislike e.g. we may have missed something and had to force solve one of the puzzles also (potential spoiler) why give you a tension bar for the lockpick and then not require it being used, why use different sound effects on the same thing if it doesn't mean anything.
However, some of it was novel and one of the puzzles we actively liked as we hadn't seen it before and it needed us to talk it out to get to the solution.
Definitely on the tricky side and requires a leap of faith for some of the solutions, but not actively disliked.
