Hey, the idea of a complete black white "side 3D"-2D is cool. Also from the start on I enjoyed the concept of a "find the way" night openworld. Somehow it let me think about a Slenderman version in 2D :D
For improvement, I would add some more music or environmental sounds to comunicate the feeling of beeing in a night forest.
Additionally, I could imagine the game to be more interesting if the wanderer does not tell in which direction the player has to go, but something like "Follow the path until the big rock and turn 90°. Walk until you stay underneath a big birch and follow the squirrle track as long as you hear the nightingale."
This way, the player is more attentive to the environment.
However I loved the flair and the very moment I did what the game expected me at the end to do, for a short moment, the games screen is black and I thought: "Oh no, this was the wrong decision!" :D
