Started when I was 16, still not ended, here is a demo of the game engine on which I work for more than 1 year. It's my first game project, so I decided to make it easy, by creating my own game workbench (a friend is making the MapEditor, I'm doing the rest), including the game engine, render engine, graphics, programmation, syntax ect. Don't wanted especially to share it, but friends wanted to play on it, so I will just share the .exe here. The source will come maybe later :)
