Scratch

Hey, I am working on a scrolling flying game. I need help, cause I have no idea what the point of the game is going to be.

I might make it were there will be different levels in which you can get 1-3 stars, depending on how fast and how many coins you collected before finishing. You could then spend your stars on upgrades. I might also make a mini map, and will probable release it when 2.0 comes out so I can take advantage of the cloning.

I want to make it were you can learn in the levels and make them balanced and stuff, so I would really appreciate links to articles or whatever about good level design.

Here is the game so far: http://scratch.mit.edu/projects/LEGOengineer261/2563723

Help is much appreciated. Thanks!
