Ecofish is a casual game for iOS platforms, based on the classic gameplay from Qix or Gal Panic. Players are challenged to draw lines across the screen using tactile input to box out space and kill enemies.
Each level can have a variety of objectives and different enemy types. There is a main game mode (campaign) of 60 levels of increased difficulty, an alternative mode which simply adds a time limit, and a third mode (treasure hunt) in which players need to focus on boxing coins instead of enemies.
Additionally, the game features an in-game shop where users can customize the main character (a little fish) with a number of different outfits and gadgets.
