I know of a trophy you only get if you draft 9 copies of a specific room in a single run, but I don’t think trophies are necessary to progress with other parts of the game.
About missing rooms: get the drafting studio, it allows you to add 8 additional rooms to your collection one by one. I don’t know anymore if the one you’re missing is among them, but I think so.
Yeah, that’s what I meant with having notes and pivoting: don’t focus on one puzzle like that. Follow all the threads and when you get the chance to make this one happen, do it.
For things related to items, you have an option to make things easier, e.g. I stored the power hammer in the coat check until I got both the coat check and a room I knew I could use the power hammer in. In the like 5 runs in between I just did other stuff, there’s always plenty to do.
Im currently enjoying there Blue Prince.
There’s nothing else like it, it’s challenging, and cozy.
If you like playing detective, and bring patience and like exploring and taking notes instead of hyper-focusing on one goal, it’s tens of hours of fun.
You might be right about the machinarium, that seems to be unusually hard to get for a sanctum key. I haven’t thought about it yet.
9 of one room is easier than that, it’s a very specific room.
