Great to see another RPG Maker title! :) I love the concept of having a zombie who’s body parts are changed to gain different upgrades, and the menu system for doing this is great. The dialogue is also fun, which is important for such games. For future development I would reccommend checking out GALVs plugins for layered graphics, and then draw the maps instead of using tiles, as this brings more life to the environments. There are several tutorials, which I used to do this in my game.
