This is a really clever idea, I haven’t seen a game with this mechanic before. The art and theme of a park ranger fit really well and add some life to it. I love how the puzzles were designed to kind of teach you tricks you could do to lead others to their campfire. If I had to change one thing, it would be nice if there was some kind of visual indicator when you were in radio range with another person.
Really fun game, I hope you keep work on this because it would make a great release. My game is linked below if you want to give it a play.
