you can set up the variables, and run the project. press space to change the backgrounds press H and S to hide and show the parameters (reclick the green flag if you want it to run again or just change the background by pressing space) good parameters: particle amount:1000 (may lag on slow devices) falling speed (pixels per second):1 lines per second:50
Instead of using clones, I used a list based system, so I can have over 300 particles (that's why it goes up to 1000) In fact, I have run some tests, and with turbo warp, you can get up to 200,000 particles, but there a lot of lag, and it is not a big improvement on what I have now, which is why I don't think it is worth the lag
