Very solid game, excellent presentation, a compelling and vivid story, and even some helpful settings.
I'm not really a fan of text based games myself but I can't point to anything that stands out in a bad way. It did take me quite a few tries to heat up the cauldron at the end, but I chose to be bad at fire so y'know, obviously it's going to be less likely than usual to fulfil that skill check. I picked stealth as my specialty so I had to go back and keep reheating the cauldron until I failed enough times to get caught for me to see the bad ending.
The only bug I noticed was of course, the "Next Chapter" bug, which just resets the game to what appears to be right when you start interacting with the cauldron, the suspicion meter persists across this reset, but it was thanks to this I was able to experience the ending where you tell him you altered the potion, and then also keep lighting the fire across many resets until it reached max so I could experience the bad ending.
It's not really a bug, but the "Sepia background" and "White background" colours are incredibly close together, to the point where I didn't think the sepia option was doing anything until I brought it into paint. I don't really know if you would want to lean a tiny bit more into that, but just thought I'd bring it up that the colours are so incredibly close that there was no feedback the setting was actually changing anything. (PS: I prefer the sepia background because it's less harsh :3)
