GemCraft Chapter 0: Prelude to GemCraft

The 8 different colored gems stand for 8 different types of attack, and they can be combined arbitrarily to prevent the enemies from passing. It is very different from the general concept of tower defense games, with rich shortcuts, smooth gameplay, and finally an exaggerated score as a feature. The new version enhances the plot and help information, and the levels and interface have been adjusted. Gems can be dragged onto towers to produce attack effects, and the gems can also be repositioned.
