I cannot share some projects because they contain Turbowarp extensions, which scratch can't load. However, If I save them as a file, and then add .wav to the end of the file I can import it in as a sound effect. Then the .wav file can be exported out by anyone. After it's exported you just need to remove the .wav and add a .sb3 instead and load it into Turbowarp and it should work fine. I learned this trick from one of @klabss projects.
Inside are the following projects: #1 pen boids - Exactly what it sounds, use space and the 1,2,3,4,5 buttons to do different things. Figure it out. #2 pitch black platformer normal/easy versions - A short platformer where all you have to see are some glitchy raycasts. #3 Julia set - Space to freeze/unfreeze, when frozen it renders with more detail. #4 generative triangle art - Make sure to use fullscreen.
