`pixelperfect` mode doesn't work

[TheLemon27]

I'm trying to make a monochromatic pixel art styled game with a small resolution, using the pixelperfect mode of this library to scale it up without it becoming a blurry mess. However, when it scales the game up, it's exactly the same as with base love2d, incredibly blurry. My code is below, pls tell me if I'm doing something wrong

local push = require "push"

local gameWidth, gameHeight = 121, 68 --fixed game resolution
local windowWidth, windowHeight = love.window.getDesktopDimensions()
windowWidth, windowHeight = windowWidth*.7, windowHeight*.7 --make the window a bit smaller than the screen itself

push:setupScreen(gameWidth, gameHeight, windowWidth, windowHeight, {pixelperfect = true})

--local baseResolution = {121, 68}
--local scaleResolution = 2
--local windowResloution = {baseResolution[1]*scaleResolution, baseResolution[2]*scaleResolution}

--push:setupScreen(baseResolution[1], baseResolution[2], windowResloution[1], windowResloution[2])
function love.load()
	
	--love.window.setMode(windowResloution[1], windowResloution[2])
	playerStartPos = {1,2,2}
	playerPos = playerStartPos
	overlayImg = love.graphics.newImage("overlay.png")
	maxHealth = 23
	maxHeat = 23
	startingHealth = 23
	startingHeat = 0
	playerHealth = startingHealth
	playerHeat = startingHeat
	gamestate = "game" --possible states: menu (in main menu) game (in the game) paused (in the pause menu) painting (in the painting minigame)
	heldItem = "none"
	lastKeyPressed = "none"
	amountOfBoardPainted = {}
    for i=1, 48 do
      amountOfBoardPainted[i] = false
    end
	numOfBoards = 0
	paintInBucket = 0
	maxPaint = 100
	
end
