I thought this wasn't bad. I will admit it got frustrating. I still have to give it credit for trying to do something different. I wouldn't recommend it, but it's in no way bad. The best part is probably how peaceful it is. There aren't any real enemies.
It just seems like a soft game. It looks weird when you do end up dying. The sounds are pretty good. I guess the sound of waves in general is just soothing. It was pretty good.
