Thanks so much for the game!
When you hit the box out of the playing screen, is that just it? Then you hit 'R' to reset? And is that the only keyboard interaction required?
I started playing this on my iPad mini (Safari), and it seems like it just needs an auto-reset once it goes off-screen to make it iPad/iPhone friendly, maybe a lives counter so you start all the way over after three fails. As it is, one fail = reload page.
I know you're working on an Apple port (and thx), but I know that a small tweak to the existing browser version would hold me a little while longer.
Thanks again!
