- Added mute UI feature to game
- Fixed UI Mute button not giving proper text feedback when it's clicked
- Fixed level display in gameplay being 1 number lower than it should be
- Fixed major issue where the save file system was allowing overwrites of lower values, so completing level 1 when 4 was completed would set progress to 1 instead of keeping the 4.
- Fixed default text remaining from the previous round played when you start a new category.
