Recursivity! @__@

A new game jam has started!
One month to make a puzzle game \c^^/
I choose to work on a very simple concept, a match-2 game where you click on the same tiles to make them disappear :)
Displaying the grid was pretty easy, but then I had to check the matching tiles!!!
And so I discovered recursivity, or oh well recursivity didn't leave me any other choice! Surprisingly, that wasn't that much difficult and using tables to stock tiles gave me a harder time!

The game is almost ready now, I learned a LOT with this new exercise c^^
What will I make next time???
