This isn't a bad little game if you can get it on sale, as the roughly two hours of playtime is a little scanty.
Graphics are pretty, music/sound effective, and voice acting tolerable.
The weakest point other than length is a profound lack of plot, or maybe I should say lack of backstory or detail in the plot. Now, I don't generally expect HO games to be brimming over with complex plot, but there are many out there that have taken time to at least flesh things out, which this didn't do well.
The other thing I will mention is that in order to play fullscreen on Windows 8 with a 4k monitor, I did have to go into the executable and disable display scaling; this is the only way I've found to get the game to scale properly. Just FYI if you are running a newer display.
So if you want a short and simple HO puzzle and don't care too much about deep plot, go ahead and grab this one if you can find it on sale. I do not recommend full price for what you get.
