I think you should consider improving the colour fill-in part. I had to paint the ql section 5 times, before the colour was finally recognized as the correct one. Other than that, great game :)
Hey! It seems that the game hasn't been working for several months now :/ Developers please fix this asap. I really liked the zombie wars so I wanna try the newest game of your series as well...
I think that a fast forward ( x2 ) button would be a nice addition because when I restarted the game to find out other possible endings I got the feeling that my character was moving a little too slow... Other than that, a great game indeed! :)
