Tetris And lava

Sure! Here's a simple implementation of Tetris game with a lava twist using HTML, JavaScript, and pictograms. Please note that this code is a simplified version and may not include all the features of a complete Tetris game.

This is a basic implementation of Tetris where you control the falling blocks with arrow keys. The objective is to create lines and clear them from the board to score points. If the blocks reach the top of the screen, it's game over. The drop speed of the blocks increases as you clear more lines.
