If you want to do the use arrow keys then you have to press left and right arrow keys to go left and right. If you choose the other one all you have to do is use your mouse pointer to move your ball. Don't touch the red points and to move on to the next wood piece you must bounce on the cracks with your ball. Enjoy! :)
I would like to thank ToadfanSchool for the original project. It became my ultimate favorite game on scratch. I hope that others will enjoy it too.
