Played this and the prequel as part of the recent bundle. Spoilers, obviously.
Liked: The meta stuff re: the framing device. The story being a flashback recontextualises the generic "correct" choices as Myx's wishful thinking, which is a neat trick. The player can predict and dread what is going to happen but they're helpless to stop it, since the past is immutable. The one "fake" choice where the text continues without input was very effective, perfectly timed to catch the player off guard. The tone and characters are much improved in MBM than in PUQFFAL imo. The prequel has some tonally strange moments (eg Myx's hunger and introduction), while everyone's motivations are constantly clear in MBM.
Disliked: The more obvious meta stuff. This is mostly tied to Digit, but the other characters eg Pip do it on occasion as well. With Digit it seems to be an intentional character trait which imo might clash with the tone later down the line.
Misc: Digit says "You're restricting nature" at some point, which should be "Your restricting nature".
