I tried it just now. It gave me an error on pressing the start button and kind of frozen. Wish I could play! :(
Hey, have you tried in fullscreen ? There is an error, but it seems to be fixed when you play in fullscreen or in another browser, such as firefox.
Sorry about that. The version in web browser has some faulty logic with the level start function. To be safe, make sure all four words are each in one of the rocks on each side before pressing play.
