Fun fact: If you set the friction and restitution values to as they would be in a perfect environment (0 friction, 1x restitution), all the particles level out, fluid, circle, and boxes alike.
I kinda expected you to remake every star system and every celestial body, the plastered-on image looks weird in comparison with the other low-graphics
Good work anyways for the solar system.
(in retrospect every celestial body would crash the game or return an "out-of-memory" error)
Have you heard of something called "Break Limit"?
Set that to 10 ns for the sponge, and watch it get actually shredded.
Also, set the right shredder to "Reversed".
Also, set the collision of the sponge to have "No self collision" enabled.
this might be slightly infuriating if you did something but then have to overwrite it then do it all over again due to the cumbersome nature of the brush (happened to me in 4)
