I too couldn't restart by pressing R, and I wasn't sure what the terminals were doing. But, I did find the (huge) egg! Nice dark atmosphere and ambiance. Spooky.

The main idea was that you are loosing bits of health if you are standing still, but monsters get you :) And terminals heal you. We just wanted to respect the "would be great features" list of CoCo Jam like "no UI" soooo it's really hard to tell without a health bar :)
Thank you for trying out the game :D
