The mechanics for the shifting hallways and rooms were awesome, it flowed nicely througout the game.
Some questions were raised tho. Does the coins make any difference if collected?
Also, the braille. What does it say? I got it to ''#AJ CO9S NE$$''
You also start to wonder who drew that picture in the cave.
I had a lot of fun playing and it's a great game.

Great job :D
