This is a classic "point and click" adventure game.
The game can be played entirely with the left mouse button (or "the mouse" if using a one button mouse with an emulator). Or with a stylus or whatever else you prefer. The right mouse button is optional for speeding up conversations or jumping quickly to another location. The keyboard can be used to toggle the music on and off, changing the speed of text or walking, show copyright details, etc., but again that is optional.
What kind of puzzles?
The puzzles are all based on the story itself, as far as possible. So if you've read the book they should seem familiar. Other than that? They involve talking to people, combining objects, finding things, and even... well let's keep that a surprise!
Any timed sequences?
There are no timed puzzles in the game, so far. I will only add timed sequences if the story demands it. But any timed puzzle will not be difficult. The game is about thinking, not running.
Any fighting?
There is no fighting. I am not a pacifist, but I am fairly close. On the rare occasions when I play a fighting game I always want to stop and find a more sensible solution. The same when I watch a movie with fighting in it, I always think there is a better way than fighting. And you don't want to be sitting next to me when the TV news comes on: I am not a fan of fighting. Maybe you disagree? Then play the game and say so. You can discuss violence and a host of other topics, and I have tried hard to be fair to other points of view. The game is not a polemic.
"No fighting" doesn't mean "no conflict." The game is filled with conflict: conflict.of ideas, conflict of personalities, conflict with one's own conscience and purpose, conflict with the system, conflict with the whole of humanity. In the biggest battles, the battle for hearts and minds where you may be hated and hopelessly outnumbered, you have to fight with your head, not your sword.
That said, Les Miserables is based on real history, and the Napoleonic war really happened. So did the French revolutionary conflicts of 1789, 1830 and 1848. Those battles are part of the story of Les Miserables, but they do not need to be part of your story - there are bigger issues at stake.
How do you play it? Mouse? Keyboard?
