Towerdefense is in your blood!
This is a great game! It s lack of story and soundeffect, but perfect for the theme and gorgeous in visual as animations.
Ohh and one more thing: the orange cell. It is cheap and actually it can kill everyting effectievly if you have 4 in one vein. But maybe in the first 3 level, and later we need the other cells as well.
Good job!
Check my game and rate it when you have time.
Have FUN :3
