Level 1: Match the wild animals

1. The game consists of tiles with images on one side and a generic back. Each image appears on precisely two tiles.
2. The player then flips over two cards, selecting them by clicking on them. If the two tiles have the same image, they remain face up. Otherwise, the tiles flip back over after a small period of time.
3. The goal of the game is to get all the tiles flipped face-up (i.e., find all the matching image pairs) in the least number of tries.
