I really liked the player character revealing mechanic! I was a little confused at first, but after reading the description, I was able to figure out how it worked! I think it would be good to limit the amount of time the player can see the player character when they hit shift though, as I found that I never really needed the extra speed I had when I couldn't see the player! The idea of navigating through a level with the use of sound is really cool, and I'd love if it were utilized more! As it is right now, there really isn't too much of a reason for the player to not hit shift! But the pixel art looks really cohesive and looks great! And the sound design fit the game's atmosphere really well! Great work!
