Played up to Chapter 2, The Cathedral (level 14). The slingshot throw feels great, and watching the fire spread and bring a whole tower down is really satisfying. Each level adds a small twist, and The Fuse was a favourite. Four kinds of torches as the whole puzzle is a perfect fit for the theme.
The night art with the big moon and the little pranksters has a lot of charm, and the 3-star "Torched!" screen makes you want to replay for the par.
The AI pipeline is impressive too: every level proven solvable by your own solver, with bots replaying them in three browsers. That's a really smart use of it.
Great job, and good luck in the jam!
