I have to agree that the puzzles were all logical, if sometimes obscure. I had to visit the walkthrough a few times to pick up on things I missed. My main beef was that collecting pieces was harder than necessary. When 2 objects were nearby, you have to zoom in, pick up one, then zoom out and back in again to pick up the other. A system of hints would be nice, rather to run through the walkthrough for a clue. I would also like to be able to pause the walkthrough, go back to the walkthrough, and pick up where I left off, rather than start it all over again. But overall I enjoyed the game.
