Very very interesting! It's basically Ultima 7 turned into an adventure game. It has the same huge level of interaction: you can move everything, search everything, etc. I would have made it so you can search inside containers like in Ultima 7, with the drawer (or chest) that appears superimposed, with the objects inside. It would be even better, because you could have objects that cover other objects, and then you have to open the drawer and then move an object to discover some hidden object underneath. This would obviously require you to redo the entire mouse-driven interface, because it requires drag and drop.
And this brings me to the only, huge flaw of this game. Why on earth didn't you make a mouse interface based on drag & drop? All you had to do was like Ultima 7. This keyboard interface is unnecessarily cumbersome, a real pain to play. Anyway, I think I could get over it. If the game is long and the puzzles are good, I would pay A LOT for this game. :) Good luck!
