bio zombie: DNA collector

This is a game aimed to teach the elementary students with basic biology knowledge such as DNA, cell, Protein, Stem cell and various body systems. Hope this game can give some biological imprinting in the kids early biological education.
There are 20 levels in the games. You can jump to any level as you want. All you need to do is to draw a line for the cartoon "professor" to walk and avoid being attacked. It is better to do the mental calculation of the path distance and the speed before the taking actual moves.
