Nicely done. 

This is so well made! The encounters were fun, the level and environment design was great, and the enemies were challenging. I died a few times, but kept at it until the end (I think? The game just closed when I got into the elevator).

Maybe to start a discussion about the health=ammo mechanic: I liked that the game forces you to make decisions about spending health to kill an enemy. For example in the last chamber before the end (crash?) many enemies would drop their health packs into the pit, which is why I decided to avoid them. Avoiding instead of killing is a risk the player has to take to save resources. I disliked that I died twice due to not paying attention to the health meter and killing myself. There is a warning sound, but in the heat of battle it is easy to miss. Maybe some mechanical changes could make it more visible, such that you can "feel" the health getting lower, for example the gun firing slower/faster. 

This game is a great basis for experimentation on the mechanics, so kudos for getting it right!
