This is a simple game where the player controls a tank at the bottom of the screen using the arrow keys, and tries to shoot down enemy tanks that appear at the top of the screen using the space bar. The player earns points for each enemy tank they shoot down. If an enemy tank reaches the bottom of the screen, the game is over. The game is designed to be played on a smartphone, with touch controls not yet implemented. Emojis are used in the score display to add some personality to the game.
