Hi Soledad:
I've only tried it a few times so far and for only a few minutes at each time. The problem, for me, is that this one is supposed to be a 'video game'. Meaning, you're supposed to meander around through this labyrinth thing until you find the 'objects' that you can practice biofeedback with. Ironically, this makes me more stressed out than before -- I want to rush and find the objects and get it over with! I don't have nearly enough free time to spend playing video games and just want to move on to the relaxation part!

But then again, maybe that's EXACTLY why I need it!
