Click the green flag button to start the game. If you do not see one of the sprites(Cat, Mouse and Watermelon) press he green flag button again and it should work. The mouse chases the cursor and the cat chases the mouse. Make the mouse run away from the cat and eat the watermelon to win.
This is the prequel of another game that I made (The killer taco). The story is that the cat is chasing the mouse and follows it all the way too a picnic mat. Then the killer taco escapes the picnic basket and starts to chase the cat in the next game.
