Nice game! I don't play many FPS, so I may not have been the intended audience for this, but I found the game fun to play anyway.
Nice coherent art style, sound design is also cool. Would have liked to see some music though, but maybe that's not what you were going for. Nice visual effects.
On the gameplay side, the core mechanics added some fun twists to the tried and true formula. I do have to say without a crosshairs on the screen, I found it kinda hard to play though, and I found I wasn't using the sword very much.
Pretty solid entry for this jam. Good job!
