How to Catch a frisbee!!

This is a brainstorm of ideas I have on the idea for my assignment

The main charcter of the game is going to have a dog running on a beach that the game player can control it with the arrows.

The aim of the game is to make the dog run around on one level of the screen and get the blue frisbee that flies around the screen bouncing off the edges of the screen. I'm not sure if it should fly around random parts of the screen or just on one level. It probably would be easier and less complicated for me to make if it was on one level.

The game player would earn points by making the dog catch the frisbee in it's mouth by pressing the spacebar to jump as the dog is one level and can't run through the sky. The dog will then return it to the owner standing on the other side of the screen who will only appear when the dog has actually caught the frisbee. When you catch the frisbee each time it will earn you 1 point. So the game lasts longer when you earn 3 points on that level you will proceed to the next level. In each level the background will be different and the fisbee behaving in a different way.

1st level-very easy, slow frisbee on 1 level of the screen

2nd level-frisbee moderate speed, frisbee still on 1 level of the screen

3rd level-frisbee fast, frisbee still on 1 level of the screen.

4th level-frisbee moderate speed alternating between 2 levels of the screen as well as going side to side

5th level-frisbee very fast and alternating between 2 levels of the screen and maybe the dog has to find the owner by answering some sort of yes or no question.
