This is really awesome! the art style is unique and creative, the controls are fairly intuitive once you understand what you are supposed to be doing, but most of all this is just a really interesting and cool idea for a puzzle (strategy?) game. There's a surprising number of little interactions and strategies you can learn from playing a few times (Like leading the priests into you to kill multiple or stranding yourself from being careless).
You could definitely build off this into a finished game if you could come up with a few more interesting mechanics that you could spread over multiple levels. Great job!
