Here are some questions that might be on your mind:

Q) Despite using classes, I am finding that the code is getting really long and unmanageable, again.

A) One of the biggest issues is the structure of our code. As we learn more C++, we will also learn ways to make the code more manageable and generally less lengthy.

Q) The sound effects seem a bit flat and unrealistic. How can they be improved?

A) One way to significantly improve the feeling the player gets from sound is to make the sound directional, as well as change the volume based on the distance from the sound source to the player character. We will use SFML's advanced sound features in the next project.
