I'm pretty sure it'll be implemented too when it is its time. I personally also know how to do games with GML (yeah, I knew Kax on a Game Maker forum before finding myself here), and since Game Maker has only a limited support for 3D games, and it's not the difficulty of "click, another click, done". I am personally really surprised about Kax making this game, I had underestimated him.

Go go, Kax GO! We're more than eagerly waiting for this game to be published!
