Luckily I had my DS4 controller and played the game. It's a quite fun mechanic, where you're controlling two people. A bit hard at the beginning, but after I died I tried speedrunning it without killing and I got to the lava part where I died again. It looks like it's randomly generated, which makes it a bit confusing at times because I'm not sure where to go, but it was fun trying to kill or not kill the NPCs after you.
