Sound

The sound needed to be done with a lot of charges. Background music as well as sound effects make a lot of fun. They even have the potential to frighten you in specific situations. For example when you hear drum roll when one of your buildings collapses and you're under pressure.

Interactions with the goos are followed by sound effects which sound nice and funny and together with the background music they generate suitable atmosphere.

Multiplayer

In this game you don't really get a multiplayer part. What you can do is building a tower out of goos you get and every meter your construction go further into the sky is being transfered to a server and you simultaneously get your actual rank.
