Block Puzzle Game for PC

This is a classic block puzzle game!
Game rules:
A block appears randomly from the top of the game, and the block will fall naturally at a uniform speed according to the grid.
In the game, use the left and right keys to control movement, the rotation key to control the rotation of the block, and the down key to accelerate the fall.
Blocks of different shapes composed of small blocks fall from the top of the screen one after another. The player adjusts the position and direction of the blocks so that they form a complete one or several horizontal bars at the bottom of the screen.
These complete horizontal bars will disappear immediately to make room for the newly fallen blocks, and the player will get a score reward.
The blocks that have not been eliminated continue to accumulate. Once they accumulate to the top of the screen, the player loses and the game ends.
