The art was nice, and it was a neat concept. It felt like there was only one path to follow and the fireflies were just above and below the path. Initially I went down when I saw the first firefly below the path and ended up in the water.
Yup we realized that maybe the game description is a bit misleading. The game goal is to exit the cave and following the fireflies and the lights guides you through the "hidden path" that leads to the exit
