No doubt C2 is the best HTML5 game engine for artists with no programing background just like me! Anyway for me making C2 able to support 3D graphics using the WebGL technology with it's splendid code blocks method will be a great move and it will make Scirra more popular in the game engines market and it will put the other code-based game engines in danger.
As a 3D Artists and indie game developers, me and my friend working on a top-down shooter game and we're modeling and rendering the levels and characters in Blender and then exporting them as a PNG's so we can use them as sprites inside of C2! we're making sure to give the illusion that the game was made in a 3D game engine but for sure it's a lot better and easier if C2 was able to render our models in real time.
I think Scirra should launch a Kickstarter campaign so we can all support them and spread the word to make C2 the first 2D\3D code blocks based game engine.
