To be honest, one of the main reasons I kept the game fairly easy was because it didn't contain as many features as I would have liked, but it's definitely something I will look at fixing in the future. The procedural level generation was definitely a key part of the game, since it is an important feature in many roguelikes. Thankfully I used Flixel for this game, so it made path-finding a breeze. I'm glad to hear that you enjoyed the game!
