This is a brief generative music environment that I made with p5.js recently, figured it's worth sharing with you all. It's still a work in progress - I'd like to add some sort of system of genetics, and more changes in sound. Also, still kind of buggy.
I don't want to say too much about how to interact with it, but I will mention that you can use all 3 mouse buttons to make noise, and the program ends when all the critters disappear.
Notes: Works best in Chrome.
