I've had this reported a couple of times now, and I get it on my own laptop as well. The HD4000 drivers don't support OpenGL 3.3 which is what I'm currently using. I do have a couple of ideas for working around this (Using GL3.0 functions or forcing GL_ES) to get the game to work on these chips, but it won't be ready in time for this demo day.
