Hidden objects game .

I learn that you need at stuff to make its again game , like this stuff ;
 - Scoring .
- Using Rollover to Highlight an Object . 
- Manage a Hidden Object List .
- Splash Screen.
- Simple Timer .
- Combine Timers and Animation .
but you proubly need more then that but this is mosts of the stuff to make it a good game and make it more colorful in the game . That there is alot of games that are cool & some of them are not but its okay because they tryed there bests so thats good . That you should do more colors . Do alot of stuff inside of it .
