Watch as the water droplets go up...and make that satisfying sound. Change the launch rate! A higher launch rate is slower, and a lower launch rate is faster. Setting it to 0 is stopping it completely, since I used a modulus method for sensing when to launch a water droplet. Use space to change the theme, and left and right to change the launch speed. Left and right arrows to adjust the launch rate.
This is my first big step into pen graphics, and I decided that this would be a great experiment. It seems that lists and using the pen is a lot faster than using sprites! (Just look at my other projects.) I hope you enjoy this satisfying experience.
