There is also a small update with changes.

-Now if you get lost, press the letter N to get a navigation line that tells you where to go. Doesn't work in all locations and doesn't work during boss battles. 

-The AI of Anubis has been worked out. If the player will be near him for too long, Anubis will get angry and accelerate. You can understand it by the visual cue on the screen when approaching Anubis. 

-Updated music in some places and replaced with author's (created by me) music.

-Added sound effects for ghostly doppelgangers when they are nearby.
