    //NOTES
        //  -Discs that spin, requiring you to run the opposite way (pepermint)
        //  -Jolly Rancher jumps (similar to MC.Honey) that make it so you can't jump
        //  -Jello that bounces you around
        //  -Pretzal hoops (maybe they spin?)

        //KNOWN BUGS
        //  -the ball does not move with the spining peppermint, currently cant figure out how to fix this
        //  -Sometimes velocity on the ball completely changes, going from very fast to very slow
