Sorry for being away for too long, I didn't do what I promised because of engine instability and my laziness. I'm currently busy with a musicial project http://www.indiegogo.com/Ultra-Pack , so I'll get back to work on early December. Btw I improved my style a lot since July, here's a pic from my commercial project
New details about the game itself: there will be WASD+Mouse, not ZX+arrows, gun will be controlled with a mouse, so gameplay will change a lot. That's all.
