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 😉

@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...
