Arduino LED Reaction Game

This is a small game I made using an Arduino Nano for the class Physical Computing (IGME 470)

The point of the game is to press the button corresponding to the light that is currently lit.
On my setup, the bottom button corresponds to the green LED, while the top button corresponds to the red LED.
The two LEDs will light up for a random amount of time, independent from one another.
Pressing the correct button while the LED is lit up will add 1 point to an internal counter.
Pressing a button while the corresponding LED is not lit up, will subtract 1 point.
There is a buzzer attached that will make sounds depending on success/failure.
By default, the win condition is to get 20 points.
Upon reaching the 20th point, a small jingle will play, signifying you won the game and then restarting.
If desired, a custom win condition can be set by holding both buttons down while the Arduino is powering on.
Both LEDs will turn on, telling you that you're now in win condition selection mode.
Pressing the button that corresponds to the green LED will increment the score by 1, starting at 1.
When the desired win condition is reached, pressing the button corresponding to the red LED will start the game.
In addition, information such as the current score, winning score, and winning score selection is printed to the Serial monitor for ease of use.

In the video I play two standard rounds, going to 20 points. I then show off the win condition selection mode, set to 4 points.
