Click the flag to display a pixelized image (it's the chocolate swirl effect from GIMP) and click the screen. It will be drawn in high resolution with antialiasing blur (aka 144p YouTube video/N64 graphics). You may use this: https://turbowarp.org/768583821
I might or might not use this to make something interesting (I did). You can import your own 32x32 images, to do that, open this site: https://xeltalliv.github.io/ScratchTools/Img2list (made by @Vadik1), set the mode to "decimal combined RGB", import your picture; you should get a text file. Then, click "See inside" in this project, import your text file into the "image" list, and it should work.
