Click on the cat sprite. Keep the "go to -200,0". This is the starting point for the cat. Add "glide" commands to your program so the cat reaches the circle. Once the cat reaches the circle, it will "level up"! Add more levels as you see fit.
This project is meant as a quick introduction to the scratch environment. We are simply teaching how to run a program and create a sequence of tasks. After students go through the first two levels, they can make more. Or they can modify the program to change its overall behavior completely. Perhaps the cat starts very small and at each level, it gets bigger and has to fit through a more complex arrangement of small hallways. Use this program as a simple introduction to Scratch. There is so much to explore! Try the tutorials or explore example projects from the community. There are also several great books to guide you. Enjoy!
