Welcome to the all new Pentastic - 2 Drawing App. Updates: >> Added a "size" slider. >> New backgrounds. To delete all of your canvas, use the flag. This app is mobile friendly. Click the colours to change the colour of the pen. Press the 'space' key on your keyboard to change backdrops. Press the 'up arrow' key on your keyboard to change the pen. Use the slider to change size. Click on flag to delete all. Press the down arrow key on your keyboard to change size, you can use slider to change size also. But use down arrow to set size above 100, which you cannot do with slider. If you want to change size, move the slider according to you and then click the flag. Then draw with your set size.
