Useless Box Game

New options:
New graphics added

From now levels are added for you to tackle them. You can also buy items from the store with the coins you collect.
The way of killing your enemy's has also changed. Now the enemy's might need more than one punch to die. Coins gain is proportional to enemy's strength. Because the game logic is changed, a button for resetting levels progress is added. This will not reset your coins budget though.

Additional fixes regarding user experience.
