Great way to reduce anxiety - needs improvement

This app is a beta version of technology being developed by researchers to reduce stress and anxiety. I find the premise - tracing lines of grass with calming background music - very soothing. However it would be nice if the grass didnt squeal when you went the wrong way. Thats stressful. And you never know which face is going to be happy and which is going to be angry. Thats a little too much like real life unpredictability and also stressful. But the idea behind this is wonderful and I highly recommend it.
