The objective is to move Luke back and forth so he catches bones and cans which add to the score and to avoid dog catchers and hawks which subtract from the score. If you get 15 points within 30 seconds, you move to the next level. If you don’t get 15 points in 30 seconds, you replay the existing level. You can continue to play to see how many levels you can reach. There is currently no specific end. I’ll add some images and possibly a video soon. Thanks for the comments.
