The point of the game is to collect all the bones, but do not even touch the junk food. Dogs do NOT like junk food. Use the arrow keys to move the dog. Use the space bar to jump. There are three bones in each level. Once you collect the three bones, the portal will start flashing. Touch it to go to the next level. If you fall of the platforms or touch junk food, you lose the game. All the bones are possible to get. I've gotten all of them before.
I used the book Coding Games in Scratch and called my game Collect the Bones, instead of Dog's Dinner.
