In Double Trouble you're playing little Rudy who is trying to make his way through the chalk world one level at a time. Use the arrow keys to move left and right and the up arrow to jump with the down arrow to duck. The space bar will allow you to interact with certain objects, such as erasers to erase the chalk, medic kits to help with your health, and pieces of chalk. Your goal will be the sponges at the end of the level. However, your path might not be linear and there will be dangers in your way. Find your way through each level and keep your health up and see what new chalk creations are in store for you in Double Trouble.
