Is This Bad Lua Form?

lua stuff

-- Creating a object and I have a load of action functions that all return self
-- which means I can chain the functions
-- and also chain after initialisation
-- I like the brevity but I'm no Lua expert. Any thoughts? :)

function CippyGame:titleScreen()

    local keepGoing = true

    local components = {
        text = TextWindowComp()
            :borders ( { 10, 20 } )
            :col ( { 1, 1, 1, 1 } )
            :size( 10 )
            :center( 100,  "AWFUL GENERIC GAME!" )
            :col ( { 1,0,1,1 } )
            :size( 3 )
            :center( 200, "PRESS START" ),
    }

    local ents = Entity { components = components }

    while keepGoing do
        local pad = self.game:getControls()
        keepGoing = pad.action.pressed == false
        ents:update()
        self:sleep()
    end

end
