My modification is animals coming from different sides and I tried adding different fruits not sure that one works.

In-order to play or move left or right player must press key "S" and the arrow keys are actually Reversed so right means left etc.

During the game, 3 types of animals appear from the top side of the screen and the goal of the game is to feed them different kinds of food before too many of them run past you. A/D or Key Left/Right Space to shoot food F to slow down time
