1. S to start the "simulation" 2. Click to shoot 3. D to change the difficulty 4. V to show difficulty level 5. Space to hide difficulty level Hit the enemy ships to get a hit. If you hit two inrapidsuccession you will get five bonus points. The green ship gives you more points than the red ship except at difficulty five where they both give you 0.5 points.
I realize this is not perfect, in fact, it is quite the opposite. But I am just beginning to learn how to use Scratch with any kind of skill so give me a break. If you would like me to change and/or add anything please tell me in the comments. Also, there is some internal inconsistency as the enemy ships overlap with the cockpit. Hits can be confused with hits taken but this is not the case, unfortunately. This is not a feature but hopefully will be in the future. The game looks worse in fullscreen but still works fine.
