Lemony Snicket’s A Series of Unfortunate Events puts you in the “unfortunate” shoes of the three Baudelaire children from the moment they find out about their parents' death and through the first three books of the
Unfortunate Events series.
You can switch between each of the three characters at will. Each character has some benefits and setbacks, forcing you to cycle through them regularly. Violet is able to climb up ladders and other objects since her younger siblings are either too small (Sunny) or scared of heights (Klaus). She also has control over the Apple Chucker.
Sunny is the smallest Baudelaire, so she can get to areas that the other two can’t. You can use her to get under tables or crawl through passageways like A/C ducts. Her main attack is (of course) her bite.
Early in the game, I found that I hardly used Klaus. His fear of heights and “bigger-than-baby sizeness” made him seem like he had no useful abilities whatsoever. If I needed to get into a tight area, I switched to Sunny; if I needed to move around on the screen and take out other baddies -- I used Violet. It wasn’t until Klaus got the ability to use the Grappling Hook and Water Pump that I found him to have any purpose at all.
The game is separated into three major sections (one for each book). The first, A Bad Beginning, puts the orphans in the incompetent hands of Count Olaf (Jim Carrey’s character in the movie). This “distant uncle” seems to have a secret agenda when it comes to the kids (or more specifically -- their inherited fortune). In this book, you will have to complete a lot of horrid chores, but eventually the three kids decide to break out. You will have to face stagehands, spiders, and eventually the White Faced Women, in order to escape the Count's custody.
The second book, The Reptile Room, puts the kids under the care of their Uncle Monty, an avid reptile collector. Once again, the Count rears his pointy-nosed head and tries to take back the children. The enemies of this book include various animals, and eventually the Hook-Handed Man.
And in The Wide Window, the children are off to live with their Aunt Josephine who lives at Lake Lachrymose. Before this book is done, Sunny, Violet, and Klaus will face leeches, bats, and large mosquitoes.
Except for the Unfortunate Events’ characters and locations, there is very little in this game that makes it stand out. I think the only real aspect that makes this game unique in any way is the fact that The Narrator (Lemony Snicket) keeps sticking his head in the way to give you tips from time to time.
