First of all: welcome back! It's great to see something new from you again. As for the game: lots of cool stuff here. Oh, I turned the NG Player off and saving works just fine, just like the game itself. As for the game, few issues here and there:
1. I got a feeling that the AR is actually a sniper rifle, single shot only, only few bullets, no burst.
2. Also fighting with fists, even with the inferno ones, sucks a bit, because the enemies hit you before you are even able to hit them.
3. I assume that the "defence" stat is related to the enemies? Because upgrading it decreases it.
4. As for the elemental damage stat: if I get it right that it applies only to the inferno fist and the Detonator?
