Very nice. You have to die and reincarnate to change location to find different weapon and ammo to defeat the god. Simple and good.
However, as I understand, locations change randomly which slows down your progression if it can be called so. After I figured that it's possible to fight the god, I ended up just dying at the locations where I already found all I needed, attempting to get to that blue slime location. It would be much better if location change was determined.
Also, pretty sad detail is that enemy's behaviour is not different. Only enemy not similar to others is that shooting robot.
