I finished it yesterday. Some of the puzzles were quite tough which surprised me for a short free game. My main frustration was that I could not save my game once I started a set of 5 photos. I would often get a bit tired after 3-4 in the set and want a break, but not want to restart the entire thing.
As a developer I know that implementing stuff like Loading/Saving is annoying so I have a feeling this was omitted for reasons like that and not because Ron et al thought it would be more fun this way.
I found the new pop-up interface worked well and I did not miss the verb bar. I would have liked to be able to click to skip dialogue as the . button is on the right side of my keyboard and awfully close to my mouse.
