Added exactly how many hits a wall can take.
'''Hammer''' - The hammer is used to dig through walls to find spheres and treasures. It makes a bigger impact on the wall than the pickaxe, digging up several
titles at a time; however, this causes the wall to collapse sooner.
'''Pickaxe''' - The pickaxe is also used to dig through walls. It makes a smaller impact on the wall than the hammer, causing fewer tiles to be dug up at a time. This causes the wall to stay strong for longer before collapsing. If anyone else is mining nearby, a pickaxe will appear on the player's screen wherever the other player hits on their screen.
