Why does my script work In Play Solo, but not Start Server / Published to Roblox?

So here is my Script using .Touched and .KeyDown .

function debounce(func)
    local isRunning = false 
    return function(...)     
        if not isRunning then
            isRunning = true
 
            func(...)  
 
            isRunning = false
        end
    end
end
 
script.Parent.Touched:connect(debounce(function(player)
    if player.Parent and game.Players:GetPlayerFromCharacter(player.Parent) then
    plr = game.Players:GetPlayerFromCharacter(player.Parent)
print("Work1")
    mouse = plr:GetMouse()
        mouse.KeyDown:connect(function(key)
            if key:lower() == "r" then
			print("Work2")
            game.Workspace.Int.Value = true
			end
		end)
    end
end))

So as you see, when the player touch's the brick, it is supposed to print "Work1". This works fine in Play Solo, but will not print using Start Server. Why does this not work? All help appreciated, Thank You. ~ Xduel

Join the game in online mode and press F9 to open the developer console. Are there any errors?

Edit: The GetMouse function only works via LocalScript. You will have to listen for collisions client-side. Here's a quote from the wiki page:

Local: This item should be used with a LocalScript in order to work as expected in online mode.
