Press the green flag. Wait for the "cutscene" to end. Thanks for playing! Use arrow keys or wasd to move. It's a pretty simple and easy game. (I have absolutely no idea why only two of "meteors" -yes that is what they are supposed to be- moves to around the map while the rest stay near the moon). Also for some reason you can win and lose at the same time (it happened to me). (The reason the mice would be on the moon is the joke that the moon is made out cheese; in case you didn't know).
I was going to try to make a game similar to Galaga but then I realized I had not idea how to. xD So enjoy the game. I COMMAND IT!!! Here is the link to part two :D https://scratch.mit.edu/projects/127594069/ (Just copy and paste it or look up Space Game Part Two. By TheGreatMe11).
