Beta 4 includes the new chapters Inventory and Power-Ups, and Deeper Dungeons. Add items with effects to the game, such as magic dungeon maps and healing potions. Extend the game to cover more than one level. Adding items helps you make the game more interesting—and poses tactical questions to the player. Is it worth risking running through a room to find a potion? Should you use your map now, or save it for later? These questions become more important as the player delves deeper into the dungeon - expanding the game to include multiple layers adds challenge, and makes resource management more of a challenge.
