Mapping: "Brain Shaker" - Analog Team 11

The concept of our game is to test players' memory and reaction times. The game starts off by first setting up, playing a start sequence of lights that is triggered when the player first turns it on. In order to begin the actual rounds, the player shakes the board. Using a random generator, a random neopixel will be chosen, staying lit up for a few seconds to give the player time to memorize the spot. By using the potentiometer, the player rotates and until they light up the pixel they were shown, using the button to choose it as their response. 

The win condition is simple: if the player locks in the correct pixel shown to them, the game responds with a green flash and plays a "win" sound, continuing the round and progressively increasing in difficulty by decreasing the amount of time the neopixel is shown for. The lose condition, on the other hand, shows a red flash and plays a "lose" sound, resetting the player's progress this far and restarting the countdown for each neopixel, decreasing the difficulty until players can progress through the rounds once more.
