1. write a new saga called gameSaga, this saga must react to GAME_START_REQUESTED events and change the game state accordingly.

2. add a new reducer called targets, and change GameLayout, to render <Target> elements for each item in this state (hint: use a default state)

3. Add a button to stop the game. When the game is stopped, it must be reset.

4. implement these rules in using sagas:

• when a target is clicked, it is destroyed,
• when a target is destroyed, the score is incremented by (1 * scoreMultiplier),
• when a target dies by itself, the lives are decremented by 1,
• each TIME_INTERVAL (defaults to 1 second), the target value decrements by 1,
• a target dies by itself when its value reaches 0,

5. update your game:

• each time a target is spawned, its coordinates are randomly chosen (but bound to the size of the game layout)
• every seconds, one target with a value of 3 is spawned
• after 5 killed targets, two are spawned every second
• after 15 killed targets, three are spawned
• whenever the player kills 3 targets without losing a life, the scoreMultiplier is doubled
• whenever the player loses one life, the scoreMultiplier is reset to 1

rule: all of this must be handled from the sagas (e.g: you can not send events from your react components to do that).

5. Add a way to increase difficulty by changing TIME_INTERVAL.

6. Make this game fun. (all bonii must be listed when you deliver your game to your bored teacher)
