Very cool game, and an awesome idea... unfortunately, some of these puzzles seem... a little illogical. I got as far as the michael atkinson one - there's no logic there. and the door puzzle? that's just plain wrong.
4/5 - you lose one star because the game ended just when I was really getting into the story. What happened next? Who are these "demons"? What's with the hammer? Who's the girl? Where did the fish come from? We need answers!
Given the ridiculous price, I really expected the final pet upgrade would be able to fly in space - too bad! :( I actually kept playing after winning just to earn enough to see that dragon in space, major let down.
You only get 3 stars, because the careful timing required for blowing smoke rings is a royal pain. It's a good game otherwise, but you REALLY should just allow people to click a button to blow the rings - either that, or don't make them so essential!
Bug found: When doing a quest it says to eliminate the marked ship - but there isn't a ship, the mark is just on open ocean, and there's no way to cancel the quest.
