First, a disclaimer! I might very well be incapable of being objective here just because I don't think I can ever get enough of Thingamus's writing style. Even simple things like the fact that my character 'swaggereth east' instead of just, you know, moving there, puts a huge grin on my face. (Also, pirates!)
So, that out of the way, in my incredibly biased opinion this was ridiculously fun to play. Everything I did or looked at had an appropriately piratey description, and I don't think I ever even saw a single default message to break the mood.
This game also has to be one of the newbie-friendliest ones I've ever seen, with a handy (in-character) tutorial, objects with clearly described uses to remove the possibility of GTV, and a simple, straightforward plot. (Also, pirates!)
If I reeeeaaally force myself, I suppose I could still think of two minor nitpicks. First, at one point a ship shows up, but afterwards is not actually visible when you look around. (Though due to the nature of this ship and its crew, I suppose if one were creative enough it could be argued that that could actually make sense, though I'm pretty sure that wasn't the intention from a gameplay standpoint.)
Secondly, the game is way, way too short. That simple, straightforward plot is a double-edged sword; without more puzzles, or at least more complex ones, it means the game is over just when it feels like is should be beginning. I wanted more content, a bigger island and a treasure that was trickier to find.
...for that matter, remotely realistic expectation or not, after leaving the island I wanted to sail around the ocean drinking grog and having adventures on the high seas. I choose to believe that the author is working on making this so EVEN AS I TYPE THIS and nothing will ever persuade me otherwise.
