The running application

Below is the default home page of the game. The UI is kept simple but colourful to keep the user's interest peaked.

On the top right, we have shown the total lives and the current lives of the user. On the top left, we show the score and level. In the center, we show the size of the snake and when the game begins, a timer is also shown here.

Here we have the first level of the game. There are no hurdles in this level because it is the easiest one. The player needs to eat fruit to get to the size 240 after which the second level appears.

Level 2 of the game is shown below:

The last level is shown below:

If you complete the last level, then you will have won the game. If you lose all the lives in between, you lose.

Hope you enjoy playing!
