double click empty green flag with no symbols click anywhere thats not the ground to spawn a cat there there's still some glitches WIP space to equip/unequip the sword(click to use sword) c to clear if you cant spawn cats just unequip the sword :) n to show/hide names (real peoples nicknames are in names also) (those cats falling in the sky cant run from the clear wall but those on the ground or underground can)
