Reclaim the filled area avoiding the enemies. While you are in the perimeter you are safe, but you have to venture into the area and return to the border to reclaim it. If the enemies touch you or your line or you touch your own line you lost a life.
There are two game modes: Arcade and Episodes. In the Arcade mode you will fight increasing number of enemies in three difficulty levels. In the Episodes mode you will need to solve 80 levels with different enemies of several kinds, on some levels you will not be safe in the perimeter!
How to play: You just need to make gestures anywhere in the screen. If you want to go up, just touch the screen and move up, if you then want to change direction, just make a gesture in the desired direction. You can combine several gestures for an incredibly fluid experiences.
