This is a simple infinite side-to-side scrolling test of water. I thought I might as well post it even though it's not very helpful or fun. I was working on this code in another game, but I needed to move it to a new project in order to code it successfully without destroying any important code.
You may recognize this as the milk from Orteil's Cookie Clicker. It is exactly what I'm working on. I'll post it once I'm finished.
