I love games that use more audio than graphics to give the player information as an interesting concept, but honestly I am not sure what I was doing in this game.
At first the footsteps and the beeping came from the same direction so I tried to walk around the source of footsteps, and then it sounds like the footsteps were behind me and the beeping, along with another high-frequency noise, in front of me, and then I died. Was that another monster?
