This game is GREAT. Like, seriously, it iterates on logic puzzles like Sudoku, Picross, Minesweeper, etc, but is all its own.
I had to go through the tutorial multiple times to really understand the 'medial' hints, but once it clicked, I've loved every moment I've spent with the game.
BUG REPORTS
I can echo though, like others have said, that pressing 'B' to try and go back to the main menu from the puzzle set selection screen crashes the console every single time, AND as an additional bug, if you have more than one profile, the option on the title screen to swap profiles is rendered outside of the viewable screen. Being able to delete profiles on the device would be nice too!
