Use the arrow keys to move or the red arrows on the screen (if you don't have arrow keys). Click on cats to interact. Some cats will say the same thing every day, some will say different things every 2 days, and some will change daily. Click on the bed to sleep. You will automatically wake up in like 3 seconds after going to sleep. The paw prints will transport you to the next area. Some paw prints will transport you to the beach from the hill. That's because I didn't make some of the other places until later, and was too lazy to change it. Click on everybody every day, because sometimes they have something special for you. Stay until you're SURE the conversation's over then leave otherwise things will happen that aren't supposed to happen. Also, the sleeping is kind of glitchy. When you wake up it automatically goes to the grand tree backdrop. I will try to fix that but no promises.
I used some ideas from another warrior cats game. Go to my profile to see it, because I remixed it and made a few changes.
