The Flag represents the finish line in any level in Kid Chameleon.
Instructions for useEdit
In order to exit a level, just touch the flag. As soon as you do, all enemies and hazards will volatilize, the holograms will vanish and your score for the level will be summed up to your total.
Then you will be transferred to the next level.
Levels have only one flag, or none. In particular, Elsewhere levels, some secret levels and most levels in the 4th stage do not have flag, and thus players must exit through a teleporter. This means that these levels will never give you any points for time, no-hit bonuses and so on.
In Boss levels, you cannot leave the level until you have killed the boss heads in question, then the flag will appear.
