Left/Right Arrow keys to move. Use scale slider to change size. (but click stage after to return focus to keys)
Credit to @papipupepappa for the (4x4) pixel character (from "Going Under"). https://scratch.mit.edu/projects/1307915712 This is a 1 costume (made with 1 pixel) animation. Only a 2-frame sequence so far, but the idea is that the number of frames is unlimited. All with 1 costume only. Coming soon: - more characters (Mario, Repton). - user-accessible editor.
