Look closely. Shortly before the killer demon there is a part of the track that may or may not have a clue. For the first "round" the answer is an "eye", so you must look closely at the walls ("trees"). In correct path lots of small eyes will pop out for a short time, there will be no eyes in wrong paths (correct path is chosen at random).
For the second round the answer is "termites". This time around the clue is aural: you have to chose the path marked with the sound of termites (I suppose). Again, wrong paths will be marked with other sounds (there are more than two wrong sounds, for added replay-ability).
The third round's answer is "death". This time around things are different. There are no right or wrong paths (each path is deadly). There are potted plants on the cracks, one of which is half-dead (the other two are healthy), but this is a "red herring". Chose any path and chop the plant with your scissors to kill it (remember, the answer is "death"!).
