Activity: make a simple scratch game. You control the cat with your cursor keys and it has to catch some bananas moving around the screen while avoiding an enemy. NOTE: It looks awful online but if you save it and open it with LibreOffice it looks OK (plus: you can edit it freely!).

1. Scratch Challenge 3
Challenge 3: Make the cat move controlled by the cursor keys and collect 3 oranges that appear
randomly scattered around the screen
Goal 1: make the cat move using the cursor keys – remember our first lesson!
Goal 2: detect if the orange is being touched and make it hide
Goal 3: make the oranges appear on a random position at the beginning of the program execution
Extra challenge: make the oranges move around
the screen randomly
Extra Challenge 2: Each time the cat grabs an orange, make the score go up by 1. You will have to create a
variable named “score”
