CHANGE LOG 

• Changed input to generic numbers 1, 2, 3, 4
• Changed game to end when reaching the end of a table rather than a specified value (authors can add or remove data from tables without changing code)
• Changed placeholder texts to better show what is coming from where.
• Updated parser errors to redirect players to valid inputs.
• Changed game to check for a portion of total answers to assign an ending, rather than using a hard number (to enable authors to add or remove data without changing code).
• Added more comments/instructions based on feedback.
