Draw... just draw. The left hand side is the palette (there is white), and just click on the middle parts to change the colors of them. Just draw, basically. This updates online, and other people can add to your drawings
This was made by using 10 colors, but I added black and white, just for convenience (Old video game sprites were 16x16, 15x16, 16x15, or 15x15, most of the time). You can draw your own thing, but someone else may change it. So... just have fun, basically. (Also, please report any bugs.) Custom blocks made this so much faster, also, so... maybe use them a bit more.
