Yes, apart from finding the weird fish (I accidentally ran into a hint about where they were, although my treasure-hunting search pattern might have turned them up anyway- it certainly turned up a few things that I suspect even Alec has forgotten about), and the last treasure, for which I used the Treasure Hunter's Map (I'm not sure what happened there- I'd scoured the area three or four times, and my search should have found that hidden passage). Oh, and I used a distinctly non-standard method of beating Octopus Prime, one that probably shouldn't be possible.
On the other hand, it took me twenty hours to reach the final boss, and an additional ten to find the last handful of treasures...
