Yes, I didn't add any audio. I'm usually the kind of developer that makes it work and then rarely comes back to make it look and sound great. More of a proof of concept approach and then I move on to another idea. I may continue to add some features to this one, like sound and perhaps nicer tile set instead of plain-old-html-css-canvas! I actually created a different word search almost 10 years ago, wow, time flies!
