+Best score is displayed next to the current combo, and in square brackets

 When a new high score is achieved, it is saved inside .vim as .combo.

 number inside (should be 0, or last best combo).

 no extension. This can be removed by deleting (or commenting) the first lines 
 in the script.
 
-The plugin is not in its final version. Right now, you will need to edit

 By default, the section B of airline-vim is overwritten to display current 
 combo. A random Runic character has been chosen to indicate the combo field.
