I would like to simulate a room in my rogue like game. 

The economy works like this, player enters a room, defeats the enemies inside, and gets money for every kill. 

I would like to balance the following:
1. Number of enemies per room with their type (I would like to have 10 types of enemies each with a name and a coin reward value for kills. )
2. Add 3 new rooms with different enemy configurations and be able to see the value earned per room and in the full run of all conected rooms
