You have to unpack the .tar.gz file. I can't remember how it's done in ununtu, but gnome and kde should be able to do this. Try rightclicking on the file and look for something like "Unpack".
Failing that, open a console and move to the folder that contains the file.
Then type tar zxvf BlitzMax118_Linux.tar.gz
