Giana Sisters: Dream Runners

I was able to get this achievement pretty easily on the level Chasm of Tears using a second controller. Near the beginning of the level you will come to a section that has 3 power ups, up on a ledge. Below the power ups were 2 areas to collect stars. You can see the area here:



What I did was move my second controller along with me until I got to the area with the 3 power ups. Each time I tried this I was able to get the cannonball power up from one of the power ups. If you don't end up getting it for some reason you can restart the level as this is very close to the beginning. It's also a good place to farm for the Stunning Twirl power up and Meteorista. Now that you have your cannonball power up, you can move a bit more to the Right in the level and you will come to an electric gate that will twist the level:



Move your second controller so that the character is standing at the edge of the ledge before the gate (Red Character in picture). It takes a bit of timing but you want to hit to use your power up before you use your main controller to go through the gate. My main character was the Yellow Person and you can see in the picture that she has the cannon ball power up. Going through the gate twists the level and powers up your cannonball. This power up takes a second to prime though so like I said it's timing. You want the cannonball to be shooting at the other character as you walk through the gate and twist the level. Took me about 3 tries but finally got it.
