First playable version

This game was way more complex than I remembered, especially since I added a lot of functionalities that ultimately were not used. It was supposed to be playable on Android, but with no hovering or right-clicking, a lot of the game was lost between versions, including left-handed support and device orientation support.

Furthermore, the original game was designed for 7x8 boards, and I expanded it to 12x13, which would barely be visible on a portable device. So for now, this is what we have. Please, do let me know of any improvements you think I can add.
