This game sounds like fun. haha. Well I enjoyed this. You offered a lot of range and music and the sound effects were well chosen and well placed. I do admit there was a part in the beginning where the gap of differentiation between the characters had narrowed and I became slightly disoriented, but as I said you offered a lot of range otherwise.
As I could hear the sound of the environment of where you were recording such as a wall or other flat surfaces causing a slight reverberation it was hard for me to envision a graveyard. I felt perhaps more critter noises like owls, crickets, wind or the rustling of leaves may have helped paint a more thorough picture.
Other than that your script was very creative and FUNNY! I liked the part where you said, "wait, can I rephrase that!?" before turning to stone. Heheh. Anyway. Four stars! Lovely job.
