New Flip Version
So I wrote a shiny little tutorial for Flip. I think the difficulty progresses much better now, and it makes the learning build up to the higher levels better. At the expense, that I think it may be a little patronizing / not allowing for learning in the early levels. I don't know, no one plays my games so I don't have any data to go off of. Anyway, if you found it too hard before, I recommend you try it again.
