Simple Rules:
1. Listen to the sequence
2. Repeat the sequence
The sequence begins with a single animal chosen randomly and adds another randomly-chosen animal to the end of the sequence each time the player follows it successfully. The level progress after each successive sequence completion, and the game ends when the player makes a mistake.
Two Game Modes:
1. Simple: Basic and limited to 4 animals.
2. Advanced: Recommended for more expert players. Gets progressively harder as more levels are completed.
