This is a project for the SDS Studio "Things to Try". It is based off of the pongs tutorial on the tips page: https://scratch.mit.edu/tips. The game gradually increases in difficulty as your progress. Check out the studio here: https://scratch.mit.edu/studios/4228332/projects/ I recently made a post about lifting gases which you can check out here: http://www.makethebrainhappy.com/2017/08/what-is-lifting-gas.html
