The game looks great. Game is too hard.
Some button above the "Z" and "X" key, possibly "D" or "R" made the screen go into some mode with blue arrows to center the screen?
The D button actually opens the dungeon editor.
In my rush to get the game uploaded for the Ludum Dare in time I forgot to remove my editors, you can even press the M button to open the map editor. :S
Sorry about the difficulty; I wanted to implement some kind of difficulty curve to the dungeons but, due to the time limit and inexperience with creating randomly-generated games, I didn't manage to ge that done in time. Something I'd definitely keep in mind incase I make a post-jam version.
Thanks for playing our game!
