You are the bouncing ball. The goal for each level is to touch the three stars. Use the left and right arrow keys move left and right. Bounce on the spring for a boost. Click on "Enter Creative Mode" to edit the levels. Click on an object to change its costume. Drag and drop objects to position them where you want them. If you want to save your changes, then you need to remix the project first.
Changed the first 60 levels! The ball sometimes goes through the platforms-sorry!
