I am trying to make a survival game and I have a problem with perlin noise. My program gives me this:

But I want something like islands or rivers.

Here's my code:

#SetUp#
import pygame, sys, random
pygame.init()
win = pygame.display.set_mode((800, 600))
pygame.display.set_caption('Isom')
x = 0
y = 0
s = 0
tilel = list()
random.seed(5843)
MAP = [random.randint(0, 1) for _ in range(192)]#Tiles#
class tile():grass = pygame.image.load('Sprites/Images/Grass.png')water = pygame.image.load('Sprites/Images/Water.png')#Loop#
while True:for key in pygame.event.get():if key.type == pygame.QUIT:pygame.quit()sys.exit()#World#for a in range(12):for b in range(16):if MAP[s] == 0:win.blit((tile.grass), (x, y))elif MAP[s] == 1:win.blit((tile.water), (x, y))x += 50s += 1x = 0y += 50x = 0y = 0s = 0#Update#pygame.display.update()
