green flag to 'home menu'. what is a contest engine, you ask? go to 'rules & notes' and the project will tell you. click for next text. the engine itself is rather difficult to use as you must draw something pretty small. Anyway, once you are done drawing (btw line is the only tool, sry), hold E key and click anywhere to extract the sprite code. Then, triple-click and ctrl+c to copy and then press D key and copy it into the renderer's variable system. finally, it will redraw your sprite. tada!
