graphic desingner and programmer cooperation

We decided that our game will be based on physics. To make things go faster and to ease cooperation between me and graphics designer I decided to build game editor. Game editor will be based on Adobe Flash and Box2d library for that platform. When it's ready, graphic designer will set elements in editor (placement and physics properties), then he will click save button and xml will be generated. Xml will describe all elements on one level, so each level will have its own xml file.

game engine

We want to make universal engine for all levels of our game. It's not so simple. First, we were trying to base our engine on Bezier curves. We draw curve and then character moves along it. Now we know that it wasn't the best idea. The better solution is to use physics engine provided by Corona SDK. So, our project starts as if from the beginning, but I think that now it should go faster.
