Arrow keys or WASD do not work. You must press those arrows at the button. Pressing the sword button will only attack the moving cat (the one on the right) if it is touching it (the hitbox is kinda off). After you reach MORE than 25 score the moving cat will move faster. ==============================================Note: if some sprites are missing than just press the green flag again.
This is my main project I worked on for like 2 days.
