Unnamed Sandbox Adventure

Indeed - it’s one of those sand simulators :) - So, why did I create this project? The idea struck me - why not interact with the sand... like, move it around? So, I decided to give it a try! I aimed to make the project run efficiently by using lists of active sand to process only the moving particles. Recently, I updated the project to include water. Simulating water is significantly more challenging and can cause more lag than sand, so please bear with any lag if you attempt to manipulate large amounts of water :)
