nice game
this is a very nice game, includes very decent puzzle problems, and it is a nice game over all!
btw to get the "free" ending you must wait in the deception level, then the light ray will disappear go to the other side, obtain the two spikes then go further ahead, you cant use the spikes in the dark walls, and when you go to the other side the narrator, a.k.a. your helper will come out of your body, like if it where your dark side, then just fall unto the middle but use your spike to delay your self and kill your dark side and jump before you go inside, and there! you got the "free" ending
