This game is going to live or die for players by how much they enjoy picross/nonogram puzzles, but if you do, the system works great and completing the puzzles is a lot of fun.

And then the story/world surrounding it is so charming. This game has such a specific sense of humor and it's exactly my jam. 

This is my go to "I've got ten minutes to do a few puzzles" game, so much that I just finished the last of the extra puzzles. Time to restart!
