Loved this game! I like that it was you and the other person calling back and forth, rather than just searching around for them. The "bad voice" being plausible enough to maybe be a person yet still creepy/suspicious really helped add to the atmosphere of the game.
Some problems I ran into were that attacking and refilling the lantern doesn't seem to do anything. With the lantern, if something was happening, some kind of feedback of that (such as a meter or animation) would be helpful. There also seemed to be bugs with the light. If I looked certain ways, it would turn off, but if I looked in a different direction, it turned back on. I think this exclusively happened when looking towards the cabin. There was also a short time of complete darkness when you first leave the cabin.
