The Gluon project is an open framework for creating and distributing games - supporting the flow of the idea all the way from the author to the player of the finished game. Our current goal for our first stable release is to create games using 2D graphics. The reasoning behind this is that the niche for this type of visual is very large and so far untapped by specialized tools. In the world of 3D games, there are solutions such as Unity3D, which provide a distribution system, but in the 2D game development world there are no tools to provide a complete eco system for both the creation, distribution and feedback gathering.
