https://projects.scratch.mit.edu/internalapi/project/402216716/get/tetris.sb is a URL from which you can download this project and run it on Scratch 1.4. The score variable seems to be not showing in the 3.0 player for unknown reasons.
Tetris, the game in which you control falling tetrominoes to form solid lines 10 units wide. Q, W, and E rotate the tetromino. A, S, and D move the tetromino. This project was made in Scratch 1.4 and is fully playable on Scratch 1.4. I made this project in 2018, then made it faster in 2020.
