First of all: quite boring. The scenes and game play are repetitive.
Secondly: It's not really fair if you make the objects the same color as the background no matter how unrealistic: e,g, - a blue lobster? It got to the point that I was searching for pale gray images in the background.
Story line is extremely engaging, almost addictive. I didn't get bored with the story, like I do with many games.
The only caveat seems to be slight typos in the HOS. I had to use a hint to find the "Spectre" which turned out to be a "Sceptre". Oh, well, still loved the game.
