Beetle Run, a fun brain teaser game with a dung beetle

You are Fred the dung beetle, and you have to roll the ball of dung into your dung beetle girlfriend's burrow to impress her!
Simply direct the dung ball into the hole in the ground by using the Arrow keys. You can roll the ball only into one direction at one move, and you need to hit objects like mushrooms to stop your move and to roll into another direction. sounds simple, but you have to think and find the right way.
