Very Quircky, though also, very fun.
The only down fall I could ever find to the game was the weird music, and whenever you came across a hard level you pretty much were stuck..possibly never ot beat it. The huge amount of animals is also what is great about the game. And I'll never forget reading the mission briefings on a few levels to find cuss words in them. One described rabbits as being "damned" trying to get you to take them out. The plot is also great, collect your old body parts through the story. Basically the game is a great hidden treasure.
The whole expierence culminates in the final level, a great game which is overlooked by many.
