Better version on my new account: https://scratch.mit.edu/projects/1119298486/ Tap to fly. Go through pipes for points. Go through pipes with icons for... other stuff. Some pipes move up and down; others might spin. Click lag button to kill the grass. Although this game is technically mobile friendly, you'd need a really high performance one because I tried it on mine, and it lagged like crazy. I made a updated version, but it has a lot of bugs: https://scratch.mit.edu/projects/685881428/
