Conserve ammo and make shots count! Click and hold for a few seconds before you shoot with the Bullgun and watch as you see a little explosion of red numbers... On level 5, when you shoot a fully charged shot, they penetrate enemies! + so others can see.
Glitch (Helpful): Place a skill (i.e. Fireball), in two skill spots. Then when they are charged and you want to use them, quickly press them simultaneously and you should be able to shoot 2 fireballs. Idk if it works with 3 or 4, but either way, that would be overkill... Hope this helps.
-Bieber when hit by water bottles- "Ouch!" or "That didn't feel good". My thoughts were " That better not have felt good! People are wasting precious water displaying their dislike of you!"
-Bieber when SHOT by a magical revolver that holds more than 6 bullets- "..." My thoughts were "He's wearing bulletproof vest that also contains bubble wrap so when shot he propels into the air..." My next thoughts were " Why would he be wearing that?", but then i remembered, "He must be expecting a concert where he would be smacked by a guy with his guitar that heard his music a few miles away and be bouncing off of his fans that seem to dress the same way depending on their hair color, but more importantly , gangsters and baseball players who want to join in on the fun. Yeah. I got nothing else to say here... 5/5.
