It may need some fine tuning, that's true. What helps best is to listen to the tutorial prior to playing the game. There you have all the rules. However, it is a task for the player to develop gimmicks so he can get an idea of the surroundings as soon as possible. A strategy I discovered that works is to strafe left and right while listening to a coordinate, so you see "across" instead of "from you to the bottom". When walking diagonal, you can detect the depth of complex corridors by doing this and getting sudden pits of low volume. Because of how the maze has been implemented, you can also reach the teapot by following a wall seamlessly. It gets a few trials to complete, indeed, but I think it finally rewards insisting players.

I also felt it was easier after my first run and started to develop techniques, but it would need more tries to get better used to it. Nevertheless it is a fun game and I hope you did not interpreted the "odd" as negative, I did not intend that way, it was rather meant as out of the ordinary :) which is not a bad thing!
