Exercise 2

This game has three levels. The basic rule of the entire game is that the ball is getting smaller and lighter gradually. If the ball is too small the ball dies. However, the ball can move faster and jump higher with a lower weight. 

The first level is simple. The ball needs to be light enough to jump to the next platform and need to be heavy enough to push down the wall and reach the end.

The second level has traps on the ground which can decrease the ball's weight and size. The player needs to avoid getting too big or too small and finds a balance to reach the end. The level contains steps and rails.

The third level has rotating obstacles and also traps. The player needs to avoid being hit by obstacles and traps. After that there are four moving platforms that need to be walk through one by one.
