This is similar to regular Tetris, but you can adjust the difficulty level. 1 for easy, 2 for easy medium, 3 for medium, 4 for hard medium, 5 for hard. Note: This can be changed at any time during the game. The hardness only changes the speed. Up arrow key for new block direction, left and right arrow keys to move, down arrow key to speed up decline. After the first block, select the difficulty. If you don't select a difficulty level, it defaults to "Super Easy."
Thanks to Jialin for the template, my mom and dad for the idea, and a couple of YouTube videos (none of which worked). Also, when a block falls, you get a hundred points. When you get a full row, you get a random amount of points, so you need some luck.
