Use arrow keys to move the sprite. There are tons of secrets that you can find by clicking random keys or experimenting around so I can't tell you more than that. In the chasing minigame press a when your cat is touching the arrow. When you do that you will hear a kind of space music. You'll get one point. Hear any other kind of sound and minus one point. press the sprite for something to happen.
This game just started off as an experiment for starting scratch. I used the scratch tutorial for how to move your sprite so thanks for that. Also i searched on youtube for how to duplicate code into other sprites so thanks to whoever that youtuber was.
