Click the flag before you press start. Sometimes the start game option does not appear unless you click the flag. use the arrow keys to move. if the cat or anyone else is talking, stop moving. when you get to level 3, keep your mouse pointed at the human, if you miss him you lose. also, go to the barn on the left side of the screen
I made this project for my sister, who loves cats a lot. I also used about a trillion broadcast blocks to make it work.
