Python Dungeon Game, My version :)

Question

This is my version of the dungeon game. Basically I just extended it with features like:

Visual map arrows which tells you the route you took in each cell kinda like tracing a line with an arrow in one of those pen and paper maze games
Warning of backtracking, picking a cell which was already picked
Option to backtrack or not backtrack and pick a new move
Visual cues on map which tells you you have escaped or died

TO DO list:

Random maze generation!

The solution seems kinda messy to me but I got it working how I wanted so I'm pretty happy haha
