Arrow keys to move and jump. Try to collect silver keys to open the house. (There is a secret way to get more lives)
I just remixed @Vasily-on-Scrath's project cat run, fixed most of the bugs, and changed some colors and sounds. And thanks to @Stella_is_a_cat for the music. (There was a glitch that I couldn't fix. If you press the stop button, the ground sort of disappears. Tell me in the comments if you think you know how to fix it.)
