@StreptoFire To charge you have to move straight forward at an enemy from a distance. I am not 100% sure that it works every time, I need some sort of clarification, but that's how I charge.
This game is good, and complete, but it needs to be upgraded. All of the instruments have sound flaws and, most recently stated by Iampureevil1, you can not make shorter notes than 1/4. These problems need to be fixed soon, because this game is becoming more frustrating than fun.
One of my all time favorite games on kongregate, 5/5. This game is fun to play and only has a few problems, not even big enough to mention. This should have never stopped being My Pet Protector, Protector is a lot more complicated and not nearly as fun. I strongly recommend that undefined makes another game in THIS series and not the Protector series.
