What surprised me when I started playing was the way the karma gates worked, and while I think pretty much every criticism regarding the game's difficulty is reasonable and well-founded, I think the karma system may actually be my favorite thing about the game!
Chimney Canopy is what sold me. I had gotten through a few hours of the Outskirts and the Heavy Industry area, and I was 3/5ths of the way to getting the Survivor achievement. It was really simple to just hunt, run, find a shelter, save, repeat, progress... the game was basically what I was expecting.
The Chimney Canopy difficulty spike wrecked me. That first wide-open three-screen room with an ungodly amount of lizards and vultures absolutely tanked my karma, and by the time I found a new shelter, I was at the absolute rock bottom.
My mentality at that point was to simply throw myself out into the world over and over, paying pretty much no attention to deaths, since I couldn't sink any lower. I ran on the rooftops even though I got snatched by vultures half of the time, just because running on the rooftops was faster and I wanted to go far.
What turned it around was finding one of those golden karma flowers that protect you from one death. The instant I ate it, I could feel the entire game twist itself inside out in my head, I could feel my paradigm shifting, everything made sense. And it happened so fast! All of the sudden, I just knew I couldn't let myself die, so I hunted, and hid, and took the safe path back to my shelter. I didn't care about making linear progress, I just needed to sleep, and eat, and sleep.
So I did. And then I did it again, and again. The level just clicked for me. I knew when a place was dangerous just by looking at it. I knew where the food would be just by instinct. And I knew that if I died, I'd be throwing away the only progress I'd made since I'd arrived
The feeling of triumph when I walked out of that same shelter with max karma and a full stomach, ready to explore, is something I've never really felt in a game. The feeling of hope when I picked that little flower, too- that's something I've never felt in a game. Having to think about the world from the point of view of an animal that lives in it instead of a Samus Aran or an Alucard that wants to breeze through it is something I don't think any other game has really captured, and the way your long term progress is gated by your short term progress is incredibly immersive.
I totally understand why this game isn't for everyone, and if I'm honest, it's still way too hard for me. But I think you guys have made something really special here, and I feel that (to some extent) people's main criticisms of the game might stem from the fact that we've never really seen a game like this.
