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

| This is the menu of Wonderful Blue | When the player fail to achieve the goal, the game is over. Player can continue at the previous level |
 |  |
| This is one of the game mode: Gold Mode. Player need to achieve the target points within the time limit. | This is another game mode: Survival Mode |
 |  |
| Initially, there are ten fish on the screen | Player can touch on the free space on the screen to release food. Multi-touch is also supported. |
 |  |
| Some of the creatures are releasing gems! Touch the gems before they disappear! | See the bubble? The creature is evolving! |
 |
|
| Enemy appear! Attack them quickly ! Multi-touch is also supported |

|---|---|---|---|
| 08-09-08 | Game's features dicussion 1.success of NDS related to our game design? 2.what type of our game is? 3.how to attract people? 4.the price setting? | 2 hrs | Done |
| 09-09-08 | Game's features dicussion 1.Focus on the simulation game 2.simple game rules and cute character 3.Attract all age group 4.have touch screen and sound detection | 3 hrs | Done |
| Week 2 | |||
| 11-09-08 | iPhone Study Group Meeting 1. Basic OpenGL ES drawing, texture mapping - how to create a texture with different size of pricture - draw different polygon by glVetexPointer and glDrawArray instead of glBegin and glEnd - how to texture map to a object when it is moving?(Problem) 2. Collision detection - how to do a 2D collision - only detect the x and y coordiantions - how to do a 3D collsion - need to detect the z coordination | 1 hr | |
| 12-09-08 | Adding other interest features 1.Enemy will appear periodically and eat the creatures 2.The game has two different modes - Gold mode — players need to collect the target amount of points within the time limit. The higher the level is, the larger amount and shorter time is - Survival mode — the number of enemies is more than the gold mode and the enemies appear more frequently. The goal of this mode is to protect the creatures from the attack of enemies. If all the creatures died within the time limit | 2 hrs | Done |
