Seems like the most important thing to know when considering this game is that it's NOT a conventional jigsaw puzzle. If you're into those and go in expecting to do your usual thing, you'll be disappointed... Or maybe pleasantly surprised, if you're open to something different.

Instead of being presented with all the puzzle pieces to sort as you please and a goal image for orientation, you just semi-blindly pick up piece after piece, see if you can find its place this time, and figure things out as you go. Trying to guess what the image is and sometimes only realizing when placing the last piece was part of the fun for me.

The special aesthetics are obviously a major selling point for this game. Cool transitions into and out of the menus and levels almost make it feel like you're playing around with some kind of Steampunk device. I liked scrolling around the map to plan my "journey" and choose the next country. Having some geography knowledge probably helps with orientation, otherwise there's some educational value (:
The enchanting music and the glassy sound effects when placing a puzzle piece complete the experience.

It's not very nice that you can't finish everything on the map without buying all the DLCs, but I guess it was easiest to implement it that way. Also understandable that they want to advertise the DLCs, especially considering the low prices for a decently long high-quality experience.
The achievements can all be... achieved? without buying DLCs.

I found it a bit too easy to accidentally move the disks instead of the puzzle pieces, but it wasn't more than a minor annoyance for me. It works fine if you drag them towards the center of the puzzle. Other people have struggled with accidentally moving puzzle pieces instead of the disk, but 1. you can just figure out the visible pieces first, 2. you can rotate the disks using your scroll wheel to avoid "misunderstandings".

Other than that? I often find games with "overwhelmingly positive" reviews overhyped, but this one deserves them imo.

More cozy and combat-free recommendations?
