That would help, but I'd actually recommend altering the behavior of the camera. I couldn't figure out what exactly affected it, but if I clicked with the mouse, the cursor would appear, and I could sometimes drag to the top and keep it there so I could see everything in front of me, but it wasn't consistent. It wasn't clear to me if the mouse affecting the view was by design or not.
In addition to the fact of orientation, you did beautiful work on the moon graphics, but at certain times (particularly walking towards the foreground), it zooms in and you can't appreciate it, so fixing the camera issue would help orientation and this at the same time :).
I'm not sure how you handled the following, but a few ideas that come to my mind are limiting the angle to a shallower one so it doesn't look so much "down" on the player, or keeping a minimum distance from the player or minimum amount of world space in the viewport, that type of thing.
