The movement of turning around oneself is a movement in itself. The fact of not moving is also another way of dealing with movement: by its absence. In my opinion, this game respects the expected subject of the game jam, since the subject is vast and the author of the jam expects an original treatment. Afterwards, this game is perhaps a little simplistic in its concept and its realization. Facing waves of zombies (who go fast, the buggers !) is unfortunately quickly repetitive. A variety of creatures (slower ones with different aesthetics) would have helped, as would getting new weapons as soon as certain milestones were reached. I did not shine with my result, but I still had fun on this game. Congrats.
