Yes, this game is absolutely fun to play, but there's something horribly wrong with the controls! You control your worm by touching the left, right or middle of the screen. By touching left of your worm, your worm moves left, right moves right and above, below or on top of your worm makes it jump. The bad thing about this is, whenever you get near the sides of the screen and want to keep moving towards it, you'll start jumping and jump off the edge of the screen (because touching near the mentioned parts of the screen makes you jump)! The problem is, as I already mentioned, the jump control. If they'd change it so you have to touch your worm to jump, walking near the edge of the screen will be possible again.
So, it's a fun game to play, but the controls are querky.
