This game is so hard or maybe I'm a noob, few tips:
Dont reset the music on death, just leave it playing, it has a feel of escalation so it shouldn't be a problem.
Didn't reach the end but I got to the zig zagging stairs, a checkpoint would be good (no worries, I know time was tight) consider that for extending the game
Make the restart a key press. eg: spacebar, otherwise I have to hold mouse and keys
Overall great feel and theme, almost had horror vibes
