Added menu controls

Hey guys!

We wanted to do this a long time ago, and it's still not how we imagined it, but it's almost there.
Right now, there is no need to use the mouse to move around in the menus, although you still can use it if you prefer it.
This was a small update so the game gets more User Friendly. Of course, the design is not complete yet!

Stay tuned for some more updates in the next days!
