The game breaks after upgrading to blue rocks. The bag number goes up, but no rock is collected anymore. Selling empties the bag number, but gives no money.
Well, I'm glad you enjoyed the art? :) . The turtle should be progressing through the level, at what speed it depends on your luck, although, if you get stuck in the wrong conrner then it's really unlikely that it will ever get out. In which chapter did you get stuck?
