Remixed to help with forum topic: https://scratch.mit.edu/discuss/topic/907941/ Use wasd to control the first balloon and arrow keys to control the second. Avoid having either balloon popped by Cheddargirl for as long as you can.
The question was how to make a movement script and also how to make a pathfinding AI that would find a target. I decided to remix cheddargirl's old project by having the player control the balloons instead of the cheddargirl sprite.
