At first before I played I thought this was just a silly parody but this is actually very well made. Nice job dev! I like how you can't save whenever you want, and how the lightning is dark and stuff, really adds to the game feel.
That said, I do think there should be some sort of game over scene or something similar if you get hit too much and/or your health reduces to zero. As it stands now, there's no real incentive to avoid traps, or use painkillers since you can't screw up.
Best of luck dev!
