Very nice!!! Played it a few times and found it quite unnerving! I think the difficulty could get a bit spicier, though, especially in how the enemies feel in combat.
Maybe having enemies with different attack ranges and attack speeds could make encounters more interesting. For example, enemies with longer-range attacks could deal more damage but attack less frequently, while short-range enemies could deal less damage but attack in faster sequences with shorter intervals between attacks. That could make the player quickly adapt to different enemy types and approaches.
But I had a ton of fun either way, don't get me wrong!
