I have added a combat system to the game. It is not 100% complete yet, but it's pretty close to fully functional (minus probable bugs). You can now attack or defend and the enemy will attack and defend also. You can defeat the enemy and you can be defeated (with a game over screen). Note that the game is not balanced at all and right now, the enemy will almost always win. I still have not added item pick ups to the game, but that shouldn't be very difficult.
