The concept was very interesting and having to micromanage all of the different things that you need to do to allow the person to survive is fun. This could be expanded quite a bit, I feel you could try just increasing the amount of things you have to keep track of like maybe add the need to breathe or blink, etc. This could really help keep the pressure on the player and if each are tied to different tasks that would be even better. Those are just my thoughts though, great game overall!
