*THIS REVIEW APPLIES ONLY TO THE NES VERSION*
I have this game on NES, and on the Wii. I prefer the NES version. It's not scary, but it can be a little unpredictable if your kid doesn't have very good puzzle solving skills. Still a pretty fun game, even if you can't beat it.
You can see a banner/advertisement for the company "Shockwave" inside the game in various places, but, who cares? They're just a internet media scripting company. Can't buy anything from them.
