Absolutely horrendous! I was told that this game is for 10 years. My daughter is absolutely frustrated with this game all because of the stupid Gulp boss. Really you had to make it insanely difficult that now my daughter is not wanting to play the game. At least make the boss reasonable to beat. Why make him able to regenerate, use everything you can use and have his own weapons. Talk about 1 sided right out of the gate. Consider this rating a -1 since there is no option for it.
