Doodle Guard: Draw to Save — draw a shield for the hero
You draw a line on a notebook page, and when you let go of your finger or mouse button, it turns into a physics object. Water balloons, bees, tomatoes from a cannon, bowling balls, and watermelons fly at the hero. Your job is to hold out until the timer runs out. A dome over the hero bounces off bees and balls, while a wall blocks the tomatoes.
Less ink — more stars
You can’t draw a line through the ground or through the hero, so you need to build your defense around them. Efficient drawings earn more stars: three stars go to the shortest line that still saves the hero. The levels never end, and along the way you can unlock 11 heroes and 7 pens. A similar challenge appears in Save the Doge, where you also use a line to protect the hero from danger.
