Yeeeeah. Cool game, I don't agree with people that complained about the loud noises :) But there could be something that shows you where to go especially in the (i think) Third Level with those big monuments. I couldn't figure out what to do next. And maybe a little introduction story, just to get people interested?
edit: I was near the cemetery tombstone but I didn't fell over, just watched someone playing it to know what to do
edit2: managed to finish the game, it's fucked up, I like it, Merzbow is proud
