Hi guys so you just stack cats on top of each other. Move your mouse to position where you want the cat, then press space to release it. Try to stack it to the MOOOOOOOON!!!!!!!!! (Tip: If the table does not appear when you click the flag, click it again). And also there MIGHT be a bug where the cat does not land all the way to the table; don't worry if that happens, just keep stacking. :|
What I really like about this game is that at the end, when you win, you get to stack cats EVERYWHERE without a limit (Well except the screen size limit)!
