Use the up, down, and right arrow keys to move your rocket ship. Press the space bar to shoot. Avoid the asteroids! As you level up the asteroids move faster!
This project is part of the Scratch Getting Unstuck 2020 activities: Create a project that uses a variable to decide when something happens. This is an iteration of my Day 4 project (https://scratch.mit.edu/projects/410634929/) The Score variable changes the level (every 10 points) and the Level variable increases the speed and frequency of the asteroids. Luckily the Level also changes the number of lasers fired at once (up to 3). There are lots of ways variables could be used to change the game play through power ups, etc.
