It was not at all obvious what you were supposed to do. I was able to figure it out when I looked at the game's Itch page, but it would've been nice to have that information in-game. I thought that the yellow glow around the priest meant 'interactable' and I didn't know what the bar on the left represented.
Overall, it's a decent little game. For the most part the strategy is just to walk in circles, but the priest is fast enough that there's not no tension.
It seems to be pretty bug-free (aside from the odd janky hitbox)
