Green flag to start. Hold the space to drastically increase speed. The up arrow shows how fast the cat is going, and the down arrow key hides it. Did I add too many features? lol
V1.1: Just the cat, bouncing around V1.2: Cat now has colors! V1.3: Added speed variable, so the cat could go faster. Also, added the interface for speed, shown with the up arrow key, and hidden with the down arrow key. V1.4: Added slow-down effect
