The art style is visually amazing, puzzles in general were okay but I had to use the book of answers with 2 of them. The message it's trying to give builds slowly and smoothly but its conclusion feels somewhat unsatisfying (bc those guys are still out there) but overall is a good and short game....

Oh right, 90% of the achievements are there either to track the general progress of players or some dumb task that the world won't react except for the "Morse code" one. So, don't pay attention to them if you have a limited time to play it (like me :p and ended mastering it)
