Hey @RobLoach, Here is Lua port i did...

-- author: Rabia Alhaffar
-- desc: Benchmarking tool to see how many bunnies can fly around the screen, using Lua.
-- input: gamepad
-- script: lua
-- version: 1.0.1

screenWidth = 240
screenHeight = 136
toolbarHeight = 6
t = 0

Bunny = {}

function Bunny:new()
  setmetatable(Bunny, self)
  self.__index = self
    self.width = 26
    self.height = 32
    self.x = math.random(0, screenWidth - self.width)
    self.y = math.random(0, screenHeight - self.height)
    self.speedX = math.random(-100, 100) / 60
    self.speedY = math.random(-100, 100) / 60
    self.sprite = 1
    return Bunny
end

function Bunny:draw()
  spr(self.sprite, self.x, self.y, 1, 1, 0, 0, 4, 4)
end

function Bunny:update()
  self.x = self.x + self.speedX
    self.y = self.x + self.speedY

    if (self.x + self.width > screenWidth) then
        self.x = screenWidth - self.width
        self.speedX = self.speedX * -1
  end
    if (self.x < 0) then
        self.x = 0
        self.speedX = self.speedX * -1
    end
    if (self.y + self.height > screenHeight) then
        self.y = screenHeight - self.height
        self.speedY = self.speedY * -1
    end
    if (self.y < toolbarHeight) then
        self.y = toolbarHeight
        self.speedY = self.speedY * -1
    end
end

FPS = {}

function FPS:new()
  setmetatable(FPS, self)
        self.__index = self
        self.value = 0
        self.frames = 0
        self.lastTime = 0
        return FPS
end

function FPS:getValue()
  if (time() - self.lastTime <= 1000) then
          self.frames = self.frames + 1
        else
          self.value = self.frames
                self.frames = 0
                self.lastTime = time()
        end
        return self.value
end

fps = FPS:new()
bunnies = {}
table.insert(bunnies, Bunny:new())

function TIC()
  -- music
        if t == 0 then
          music(0)
        end
        if t == 6*64*2.375 then
          music(1)
        end
        t = t + 1

        -- Input
        if btn(0) then
          for i = 1, 5 do
                  table.insert(bunnies, Bunny:new())
                end
        end
        if btn(1) then
          for i = 1, 5 do
                  table.remove(bunnies, i)
                end
        end

        -- Update
        for i, item in pairs(bunnies) do
          item:update()
        end

        -- Draw
        cls(15)
        for i, item in pairs(bunnies) do
          item:draw()
        end

        rect(0, 0, screenWidth, toolbarHeight, 0)
     print("Bunnies: " .. #bunnies, 1, 0, 11, false, 1, false)
     print("FPS: " .. fps:getValue(), screenWidth / 2, 0, 11, false, 1, false)
end

But it's garbled sorry...

This is great, Rabios! Thanks so much! Would you like me to make the commit? If you push up a Pull Request, you'll end up getting author credits :wink:

@RobLoach Unfortunately i'm new to TIC-80 so i got stuck with injecting assets to the cartridge (Very sorry)

I know it's shame to ask for but mind if you made cartridge, Oh i should note that there is possibility where code maybe need to edit somewhere (I used this way of OOP in Lua which is metatables...)

But i included my name in code, So even if you commit at least keep my name on code and add your one if you don't mind...

Fun info: My name is Rabia lol...

About fennel, I maybe need some time to learn about it, But maybe will be in this week!

[RobLoach]

Added it... There's something wrong with integer/float types.

Hm...Isn't when downgrading bunnies count and reaches smaller than 0, Right...
