Add  var to manage the game states for level 1
Level1-1-Gamestates==1 => show 4 fishes, crab must be "touched" to change to next gamestate

Level1-1-Gamestates==2 => show 1 dolphin, turtle must be "touched" to change to next gamestate

Level1-1-Gamestates==3 => game ended, the user can go to the next scene by clicking at the beach
add change var effect to set var Level1-1-Gamestates to 1 when user goes from scene 1 to 2
Move some components leaving an empty space in the center of the screen to show there the components implied in this first minigame
seagull is a variable debugger => it disappear when  Level-1-Gamestates == 1

besides, the user can't change the scene until he/she finish the first minigame
Crab and turtle "touchs" logic
Elements to be guessed "visibility"
