I like this.
I got stuck after I picked up the mace, the door leading to the crystal is locked and I didn't notice anywhere else to go.
The combat is interesting, usually directional attacks are paired with slower movement, but I think it works as long as you have room to maneuver.
Although I would suggest either binding an attack to the "no direction" direction, or never resetting the attack direction in the first place.
Promising game, I hope to see more.
