Improved timer to increase the challenge of puzzles

Hello, the timer introduced in yesterday's update has just received some major improvements. 

Update: 

- Time to beat: The time to beat is modified according to the size of the puzzle. It is also displayed in the puzzle details.

- Best time : The best time done is displayed in the puzzle details before launching it or after finishing it

- Current time: The time done during the run is displayed at the end of the puzzle to allow comparison with the time to beat or its best time. If you fail to beat the time, the puzzle does not stop and your run time will be equal to the time to beat, this will change very quickly.

Game Design:

I think this timer will add to the challenge of completing the puzzles. Afterwards, it will be mandatory to finish in time, the time to beat will be calculated according to more complex parameters and doing a really good time will reward the player.

All feedback is greatly appreciated and thank you for reading!
