Nice little entry, graphics and pixel-art animations are definitely the cherry on top here.
It's always nice to have a little tutorial at the beginning of the game, especially when mechanics aren't obvious (just like here) but I can understand that there wasn't enough time for that during the jam. Some additional UI showing what stance you're currently in would be really helpful. Still, the most striking thing to me was the lack of arena boundaries: nothing stopped me from simply running away from the ghosts into a sterile place where only void keeps you company.
That being said the concept is very fun and with some improvements I'm sure the project will turn out amazing ;)
Keep up the good work!
