Thats really cool one! Graphics a really good as well as Idea, but here is a little problem I faced: It is really hard to read trough demons orders because of camera jittering. You often have to stop to read the required order and that is throwing out immersion in that fast-paced process. (Also I had some problems with lines appearing on the screen as visual bug but idk, maybe it is problem of my browser)
Nevertheless - very good job mate!
