First alpha release

Since the release of the first prototype a few days ago, the game has been recoded to start looking like its final version. A lot of work remains to be done and I'm still working on the engine. The graphic side is very, very unfinished. Lots of CSS block still have graphic colored border (that will disapear in the future) giving to the game this strange look for now, but that's okay at this step.

In the next update I will try to implement :
- New series of artifacts (with a simple visual).
- The "Statistics" menu
- The "Shop" menu

I'm carefully finishing the map of the maze and I'll start coding it within a month if everything works.
And then, I might as well tell you that it will start to look good!
