pygame wasd 키보드 안됌

pygame을 이용해 패드 컨트롤러 같은 걸 만드려고 하는데, 방향키만 입력이 되고 스페이스와 나머지 키들은 입력이 안 됩니다. 왜 그럴까요? 코드는 이렇습니다.

import pygame

import sys

import keyboard

from pygame.locals import QUIT

pygame.init()

pygame.display.set_caption("Test Window")

Surface = pygame.display.set_mode((600,600))

FPSCLOCK = pygame.time.Clock()

def main():

    while True:

        Surface.fill((0,0,0))

        c1=255

        c2=255

        c3=255

        c4=255

        c5=255

        c6=255

        c7=255

        c8=255

        c9=255

        for event in pygame.event.get():

            if event.type == QUIT:

                pygame.quit()

                sys.exit()

        if event.type == pygame.KEYDOWN: 

            if event.key == pygame.K_LEFT: 

                c1 = 100 

            elif event.key == pygame.K_RIGHT: 

                c2 = 20

            elif event.key == pygame.K_UP: 

                c3 = 80

            elif event.key == pygame.K_DOWN: 

                c4 = 40

            elif event.key == pygame.K_SPACE: 

                c5 = 10

            elif event.key == pygame.K_w: 

                c6 = 75

            elif event.key == pygame.K_a: 

                c7 = 40

            elif event.key == pygame.K_s: 

                c8 = 100

            elif event.key == pygame.K_d: 

                c9 = 200

        pygame.draw.rect(Surface,(255,c1,255),(15,15,180,180))

        pygame.draw.rect(Surface,(c3,255,255),(210,15,180,180))

        pygame.draw.rect(Surface,(255,255,c2),(405,15,180,180))

        pygame.draw.rect(Surface,(c4,c4,255),(15,210,180,180))

        pygame.draw.rect(Surface,(255,c5,c5),(210,210,180,180))

        pygame.draw.rect(Surface,(c6,255,c6),(405,210,180,180))

        pygame.draw.rect(Surface,(255,c7,c7),(15,405,180,180))

        pygame.draw.rect(Surface,(255,c8,c8),(210,405,180,180))

        pygame.draw.rect(Surface,(c9,255,255),(405,405,180,180))

        pygame.display.update()

        FPSCLOCK.tick(120)

if __name__ == '__main__':

    main()
