This is an absolutely brilliant idea that works really well in practice. It's so intense!

Fun mechanic! Good level design too.

Interesting idea and sets the mood well. The mechanic was fun and game was enjoyable to play through.

Nice job. I love the theme and the gameplay hook is a really good idea in both that it's a fun mechanic and adds to the atmosphere. There were some issues, like I could survive and escape after dying if I was close enough to the exit, and I didn't feel like I needed to move the player much until all enemies were dead, but overall I think you have made a very creative entry and did well with the theme!
