+--- Day 13: Care Package ---
+
+   As you ponder the solitude of space and the ever-increasing three-hour roundtrip for messages between you and Earth, you
+   notice that the Space Mail Indicator Light is blinking. To help keep you sane, the Elves have sent you a care package.
+
+   It's a new game for the ship's arcade cabinet! Unfortunately, the arcade is all the way on the other end of the ship. Surely,
+   it won't be hard to build your own - the care package even comes with schematics.
+
+   The arcade cabinet runs Intcode software like the game the Elves sent (your puzzle input). It has a primitive screen capable
+   of drawing square tiles on a grid. The software draws tiles to the screen with output instructions: every three output
+   instructions specify the x position (distance from the left), y position (distance from the top), and tile id. The tile id is
+   interpreted as follows:
+
+     • 0 is an empty tile. No game object appears in this tile.
+     • 1 is a wall tile. Walls are indestructible barriers.
+     • 2 is a block tile. Blocks can be broken by the ball.
+     • 3 is a horizontal paddle tile. The paddle is indestructible.
+     • 4 is a ball tile. The ball moves diagonally and bounces off objects.
+
+   For example, a sequence of output values like 1,2,3,6,5,4 would draw a horizontal paddle tile (1 tile from the left and 2
+   tiles from the top) and a ball tile (6 tiles from the left and 5 tiles from the top).
+
+   Start the game. How many block tiles are on the screen when the game exits?
+
+   Your puzzle answer was 284.
+
+--- Part Two ---
+
+   The game didn't run because you didn't put in any quarters. Unfortunately, you did not bring any quarters. Memory address 0
+   represents the number of quarters that have been inserted; set it to 2 to play for free.
+
+   The arcade cabinet has a joystick that can move left and right. The software reads the position of the joystick with input
+   instructions:
+
+     • If the joystick is in the neutral position, provide 0.
+     • If the joystick is tilted to the left, provide -1.
+     • If the joystick is tilted to the right, provide 1.
+
+   The arcade cabinet also has a segment display capable of showing a single number that represents the player's current score.
+   When three output instructions specify X=-1, Y=0, the third output instruction is not a tile; the value instead specifies the
+   new score to show in the segment display. For example, a sequence of output values like -1,0,12345 would show 12345 as the
+   player's current score.
+
+   Beat the game by breaking all the blocks. What is your score after the last block is broken?
+
+   Your puzzle answer was 13581.
+
+   Both parts of this puzzle are complete! They provide two gold stars: **
+
+   At this point, all that is left is for you to admire your Advent calendar.
+
+   If you still want to see it, you can get your puzzle input.
