i would have made a 3D game , but i know no good 3D designer , and it would have taken much more time than this one , specially i barely have time for this one as everyone can see but it i'll finish it anyways .

plus a web-browser game is not from the past , there are alot of browser based games running on facebook for example .

and maybe in the future this game will become in 3D (am building the engine in a way that could be used for a 3D later on )

plus browser-based games (not flash ones) could be played anywhere and anytime from your phone and PC , i believe sooner or later a 3D engine for CSS3 will be available (i've seen some people who built 3D mazes in CSS ! so it would be possible if not with CSS3 then maybe CSS4 ?)
