You guys made such a damn good game! The dungeons are so fun, especially in Nightmare mode. Whoever came up with the epiphany system, give that person or team a raise. The fact that you can build your characters in so many ways, is just amazing. You had a few hiccups at launch, but you communicated and got them fixed. The game isn't easy, it's very challenging in a good and addicting way. Keep it up devs. 👏👏👏

I just did a Chaos run and didn't have the insanity mode on because the game auto turns it off after a run. If it was on, I could have possibly had a really fun build for a couple of my characters. And now I might not ever get the exact build I just had because of this. Please make it so it doesn't automatically turn off this mode in chaos! Or at least give a confirmation when starting a run to make sure you're in the right mode. (I'm so sad rn dude 🫠)

This game has a catching story with mechanics I've yet to see in any game. I appreciate the focus on mental health and responses under stressful situations and needing to look out for your agents in more than just physical health. I do wish the main character you had the option to be male or female rather than just male, would make the experience more immersive.
