One of the most useful features is the leftmost and rightmost block movement. This means you can move a block all the way to the left or right of the screen with just one key press. I've also included a counter-clockwise rotation feature, which makes it easier to get your blocks into the right position.
If you're interested in checking it out, you can find the source code on my GitHub repo. Thanks for taking the time to read this, and I hope you enjoy playing my Tetris game! https://github.com/genieCS/retris
