Very cool! You've done a great job using Pico-8 to make something really creepy and atmospheric. Was a little confused about the story, but I think I got the gist, and it was definitely creeping me out! Might need to play again and see if I can follow it a little better and try for the other endings.
Would love to see more! Keep making cool stuff :)
Edit: Also was fun to see another game called Dead Air about spooky radio signals hehe :)
