Fun Fact: Dr Brukhonenko (crazy scientist guy that takes over the lab) is a reference to a Soviet scientist in the 1940s that is credited with reanimating a dog's severed head, among other weird resurrection experiments. They even filmed it. Look up "Experiments in the Revival of Organisms" from 1940. Terrifying.
This game is incredible. Not only did I enjoy putting the music together, but I also found a way to play around with the pieces, adding and taking away parts to give a different sound each time. And while the hidden object part was fun as well, I would suggest that the developer(s) polish the interface a bit to make it more player-friendly.
This game has something a lot of other games don't have; intrigue. Even if a game has excellent graphics, it won't succeed if the game itself is not worth playing. I, for one, have enjoyed playing these games and I'm really excited to see what happens next in the saga.
