I thought I'd offer feedback as I'm going through the Tutorial. In relation to some of the other similar games, the pace seems to be very slow. I think the pace should be quicker for the initial part of the game. 16 mins for Haggling seems a little long since there is nothing else to do until it's completed.
There should be lots to do in the first part of the game to introduce all of the game elements, why the system works the way it does, etc. I don't think any of the beginning elements should take longer than about a minute or so.
Also, the Tutorial system does seem to get in the way alot. If there is a way to make it a widget box like the chat box off to the right, it would be less intrusive.
Just my thoughts. :)
