Game Design Document: Cosmic Express
This document was created as party of a university module, in which we’ve had to pick a puzzle game of our choice and create a (potential) game design document for it. In total there were six topics given for the document: Modification Core, Family Tree, Target Group Analyzation, Core Loop and Level Design.
The content of the game design document is completely speculative, I am in no way involved into the development of Cosmic Express. If you want to support the game and the developers, you can go to their website.
