Not all that perfect but I can't find a game like this any better.
The sound/music is also very good for the type of game (especially with some good scare scenes)
The play control takes a bit of learning though and at times can be frustrating (for instance you'll have to click on an exact area).
Overall, the game is decent but is like people agree too short (for instance: We never meet Jerry in person nor get the power working). Also, the game is rather difficult to follow without a walk through (for instance you have to call Jerry several times, and if you haven't completed all tasks the line will be busy and other times you might have already done them so you'll just have to keep calling him back up).
But overall if you liked the games above I listed, you should like this one.
