Marian, I liked the game enough that I was annoyed when I had to take a break to go to the grocery store and fix lunch.
Hey, that's important information that should be included in all game analyses!

I only played the first hour of the demo, but "good" is how I would have rated the game, as well. And, like you, "good" warrants a game credit.
It seems to me that the developers were trying to do something a little bit different here, and I give them kudos for that. I also thought that the "spot the differences," although not one of my favorites, were easier to see and more well defined than in some of the games that I have played. I also liked the word puzzles--give me a word puzzle mini-game over a mechanical puzzle any day, as I find those more enjoyable. And, even though some of the objects were hard to see, that is the case in most of the HOGS that I have played, and I found the use of color in this game much easier on my eyes overall.
So, time to sit back and wait for the release of the patched version...
