1) Make the bear introduce the game before it starts. Try test-to-speech. 2) Make the bear move back and forth across the bottom with the mouse pointer, but not up the screen! 3) Fix the food code so the food can actually fall to the bottom, then hide. 4) Make the food return to the top to fall again,. 5) Set conditions for winning and losing- you will need variables. Extra time? Make the bear turn an unhealthy color if it eats too many doughnuts! (Use another variable! Change the costumes of the bear.)
This is a game starter for people who are learning to program. IT IS NOT WORKING ON PURPOSE so you can increase your skills to fix it.
