====== Game Description ======

  * Wonderful Blue

The game will simulate a aquarium. There will several kind of marine creatures, such as fish, shark, octopus, lobster, etc.\\
Initially, there will be only two or three fish. Players need to buy food to feed the fish. Then the fish will grow and when they become bigger and bigger, they will drop emerald, ruby, sapphire, diamond, etc according to the size of the fish. Different gem give different amount of point and the player need to touch the gems in order to collect them.
The point is used to buy thing like food, fish and used to upgrade food, weapon and more important, to proceed to the next level.\\
Why do we need weapon? Since monsters will appear periodically, we need weapons to destory them and protect the marine life. If all the fish are eaten by the monster, game is over.If the player can earn a target amount of point, he can proceed to the next level.\\
In the next level, there will be one more kind of marine creature or may be more weapons.
Also, after completing each level, there will be a pet that can help playing the game, e.g. can make the fish dropping more gems, can protect the fish fromt the monster, can help attacking the monster, can help collecting the gems, etc.\\

====== Draft Interface ======
{{fyp:design.jpg?600x375|}}

====== Game Features ======

  * Use multi-touch to release food
  * Use gesture to change the type of food to feed different kind of creatures
  * When monster appear, use accelerometer to control the movement of the fish to keep away from the monsters
  * Use gesture to make a special attack to the monster

====== Techniques applied ======

  * Multi-touch
  * Gesture
  * Accelerometer
  * Sound
  * 2D graphics
