I have mixed feelings on this one. The graphics, music and SFX are wonderful and really create a spooky/exciting vibe for the game. Great job on that!
However, I find using the commands instead of just the arrow keys to be really tedious. Where I think this could have been improved was being able to chain commands together like LRDDDULR and pressing enter to have them executed at once. Otherwise, without the chaining ability, you're just using two keystrokes for something that normally takes one, and it's less intuitive. Even though it's really creative and fun to type the commands at first, it gets tedious quickly.
Super creative idea, though, and polished execution!
