I stumbled across this page and made an attempt at using Funnel in the iPhone/iPad app Codea, it was quite easy to get Funnel running! :)

-- Fennel example of a rect drawn where the user touches the screen. 
function setup()
  viewer.mode = FULLSCREEN
  c = fennel.eval([[
(lambda [] 
  (background 0)
  (rectMode CENTER)
  (fill 95 80 233)
  (rect (. CurrentTouch "x")
        (. CurrentTouch "y") 50 50)
)
  ]])
end
function draw()
  c()
end

It shouldn’t be a problem in terms of the rules of the jam, but it will be difficult to get people to rate your game if they can’t run it on their computer.
