I love how Courtney says things like "Wow, look at the zero." or "I have limited ammunitions!" whenever I try to fire when I'm out of darts, or when I collect a rainbow candy to clear the board. Also, did you do the drawings yourself? Because it's incredible!
Personally, I didn't have a lot of trouble with the controls since I could just collect the rainbow candies to earn a bunch of points. However, I think it's better if the player could shoot the darts with a single click instead of a double click. Other than that, this is a pretty solid game. Great job on your game!
