Fun little game! What I appreciate is that it somehow feels like a finished game, despite obviously being a demo for a jam. One game design note: at first I thought that souls are inside the graves and was maniacally used the hard on every single grave in the hope to find one that contains the soul. Not sure how you can fix that or even whether you should fix it at all, maybe I’m just silly :D Anyways, good job!
(btw, try & rate my game if you like shooters)
