1,2,3,4,5,6,7,8,9 to make your pen bigger or smaller! Click space to erase everything. Click "z" and write the color you want to draw with and click enter! Use lowercased letters and you need to spell the word correctly or it will not work. Use "m" to erase! And of course you can change how big your eraser will be by using the numbers.
Have fun!
