Version 7

After the last round of bug fixes, I decided to make a couple of changes:

• FIX: Score is now reset properly for each game.
• FIX: Now your hit points do not replenish when you go to the next level. 
• CHANGE: They are now only 1 or 2 health potions on each level.

I am hoping these changes make the game a little more challenging and fun. :-)
