create a simple 2D representing a dungeon that the player is trapped in

You are creating a simple 2D game representing a dungeon that the player is trapped in. The only exit is blocked by a boulder that can only be moved if the player has eaten enough energy bars. Luckily there are plenty of energy bars scattered throughout the dungeon left by previous explorers, but unfortunately there are also ancient evil mummies wandering randomly around the dungeon that will cause the player to lose a life if they touch the player. The only defense the player has are spades that can also be found, these allow the player to dig a hole that traps any mummy that falls in - however the player will also lose a life if they fall in! The game is won if enough energy bars are collected, the boulder moved and the exit is reached before the player runs out of lives
