Like the style and theme. Just my suggestions below:

Since it is on PC, you should consider the movement to tied to mouse direction (and maybe together with mouse button down) instead of buttons to give it a much smoother movement as buttons feel very clunky.

Also, you can consider making the sound wave detection pinging off the blind fella more often as many a times, I actually move into attacks but the sound wave detection was lagging a second at my previous position.

Overall, it feels nice, keep it up.

Just some thoughts

- music overlaps if u click continue game
- it is unclear what the player needs to do / what is my purpose ?
- everything else seems ok
