## Description

5/5 - (1 vote)

In this assignment, you will use Javascript and html to implement a simplified Tetris game.

The simplified Tetris game consists of a 2D grid and 4 types of rectangle pieces. The rectangle pieces fall, one at a
time, onto the grid.

Users can move the rectangle pieces to the left and right as they fall. Once an entire row is
formed, the row collapses. The game ends when the stack of rectangle pieces reaches the top of the canvas and no
new rectangle pieces are able to enter.

In this assignment, you will create a canvas, which is a 2D grid. The height of the canvas is 240 and the width is
180.

You will implement the following four rectangle piece (which are different from the tetrimino pieces in the
standard Tetris game):
Size: 20*20 Size: 40(L)*20(W) size: 60(L)*20(W) size:80(L)*20(W)

The rectangle pieces will appear randomly. You can use Math.random() and Math.floor() to randomly generate an
integer between 1 and 4, which is used to determine which rectangle piece will appear next:

You will also create two buttons (left and right) to control the movement of the rectangle pieces. The rectangle
pieces can be moved to two directions: left and right, by 20 unless it hits a wall or another rectangle pieces.
