Structurally very similar to the first game: more fetch quests, more fun NPCs, more wildly imaginative locales to explore. This familiarity is likely a deliberate choice, designed to subvert the ending of LMG1. Where you previously (Spoiler - click to show)threatened violence to get what you want, this time round everything points to a similar resolution, but that doesn't fly and you need to find a more peaceful way, more in keeping with the protagonist's personality.
The "classic fairytale re-imagined" is one of the most heavily over-represented genres in IF, but when Ryan Veeder does it, you pay attention. You play the titular match girl, freezing to death on a street corner but able to teleport to different times/places/worlds by striking matches. Gamplay is super-straightforward fetch quests: find an object / find the right NPC to give it to, or find an NPC / figure out what object they would like. Superluminal Vagrant Twin-esque. It's elegant, clean and simple. Locations are varied and surprising. NPCs are deftly characterized and full of life, despite how little they actually say and do.
