Click the green flag to begin. Watch the fish swim around! If you turn on video motion, you can make frantic movements to scare the koi xD watch the water lilies in the water as well Yeah, that's it :| For those of you who want to know how to turn on video motion, click inside the project, and under the "sensing" section, there will be a block called "turn video on". Click this, and your browser may ask if you want to turn on your camera. Then click "allow" :)
