The art is nice, but there is no sound at all. In the "fear" level, the jump to the invisible platform is too big and it's not intuitive that you have to move the box backwards. And in the "is it worth it?" level, it is very difficult to jump over the gears. Once you then finally get past them, you get killed by spikes from the sky. After that I just quit the game. So to answer your question, no it isn't worth it.
