I've played a few different 1st person games in this jam, and the idea of the dice being affected by what direction you're facing is one of the more interesting ideas. As some people have mentioned, it would be nice for the dice to rotate, so that you can't just stand at one side of the room the whole time to get your full 6 damage.
My only criticism is the polish, but have seen that you ran into issues. It would be great to have a satisfying sound effect, for example.
But ultimately, this was a really cool concept, and there's something always fun about taking down a horde of skeletons.
