Great game! Everything worked no problems for me. Great example of how a good story is far more important than pretty graphics/animations - note that I thought the art style was fine (i.e. did not detract from the gameplay and was detailed enough to be interesting, but not so detailed as to be overwhelming).
Did not feel particularly challenged by anything - if you follow what you read, then there are no problems (that's actually a good thing!) - thankfully the narrative dragged me along.
I would have liked a few more click-able item descriptions, just to get a little consistency: like I can click one barrel, but not the other - or I can click part of the ocean (not the whole ocean?!), but can't click the ship (which would be the obvious thing to stare at).
Music set the tone quite well.
