Spooky stuff! The concept is good, having to navigate the 2D maze while making sure that the monster doesn't sneak up on you can make for a very intense experience. The sound of the breathing very definitely heightened that intensity.
The implementation of distracting the monster by throwing objects did not seem to work for me, it was always interested in moving to where I was rather than the direction of a thrown object. Because of this I wasn't able to escape through the maze.
The only possible way to succeed that I could come up with was to make a tiny bit of progress between running loops around the starting area. That keeps the monster a few steps behind and buys only a couple of seconds to try and get somewhere in the maze. Heading to the lower area was more likely to end in being cornered.
