Click the green flag and then an introduction page will come. Wait a few seconds and the page will switch to a dog. Click on anything on the dog that you would like to change. You can change the ears color and shape, the head and body color, the eyes and tail. If you click the spacebar you will be able to change the background color. When you are going through the ears there are many options. There is also a different shape of ears that can be used as cat ears.
It took me about 3 hours to make all the shapes and put the colors and then do the coding part but it was worth it. Comment below what other ideas you want me to do. Hope you all enjoy!
