Zelda: Nell's Onyx Watch (alpha)

This is a recreation of the 1989 Zelda Nelsonic Game Watch in GB Studio. 

This alpha version is provided to get feedback from the community in order to make it more like the original LCD game. 

Instructions:

• Z key = A button: Pick up item, Drop Bomb 
• X key = B button: Use Boomerang / Sword 
• Arrow keys = Dpad: Move 
• Enter key = Start: Pause

You can only kill Iron Balls if you have the Boomerang. You can only kill bats if you have the sword. The Sword only appears once you have killed all the iron balls. 

Pick up the key to open the door to the next room.

Do you have a copy of the original LCD watch? I have only been able to watch YouTube videos of it and so I have not been able to verify its functionality perfectly. Here are some questions I have about how it actually works. With these questions answered, I should be able to finalize this game to be a gameplay-perfect recreation of the original. 

1. The instruction booklet states: “Link must get away before the bomb explodes or else Link loses all his lives.” How close can link be when the bomb explodes? Does he have to be right next to the bomb to trigger a Game Over, or does he have to be at the far side of the map? (This alpha version doesn't simulate this at all.)
2. What are the rules for when a heart appears? Does it appear only in certain levels, or does it appear at random? Or when Link’s health is low enough? How long does it stay on screen before (This alpha version currently assumes a heart appears in certain levels, and is available for a short amount of time before it disappears.)
3. When is the player hurt by enemy movement? Does the player only need to be next to the enemy on its move step, or does the player have to have a certain orientation to the enemy on its move step? (This alpha version currently assumes that if an enemy and Link are in the same position in the LCD grid at the start of the enemy's move step, then Link takes damage.)
4. Can the player attack an enemy from either side, or does the player have to have a certain orientation with the enemies to do attack them? (This alpha version assumes that Link can attack enemies to the left or right of him when B is pressed and he has the right weapon.)
5. Does the player being next to or near an enemy change its movement? Will it still move randomly? Will it move through the player? Will it stay still? (This alpha version assumes that enemy movement is entirely random and unaffected by the player's position.)
6. Does the player die ("Game Over") when they lose health and the lives display is at 0, or when it is at 1? (This alpha version assumes that if the lives display shows 1 shield, then you have 1 extra life remaining. Game Over happens when you lose all health and have no "shields" remaining.)
