Had no idea this existed until not too long ago. It's pretty similar to the first game, though it's wayyyy bigger. Each puzzle is split up into four individual grids which each have their own puzzles, so they can take up to 20 minutes to complete at times, especially in the later levels where things become more complex. Still, it's a lot of fun to blast through them. I did only technically beat half of the game, however, as there is a mode where you play as Wario, and the game doesn't tell you when you make a mistake, which adds a layer of depth to the puzzle solving I don't really enjoy. I didn't do many puzzles on Wario's mode but I completed Mario's which felt plenty satisfying. 4/6
