As a connoisseur of puzzle games, I can say that this ranks among some of the absolute best. It's the ultimate collection of Mr. Driller and driller mini-games. The soundtrack is full of cute bangers. And there's even a hardcore rogue-like mode called the Hole of Druaga where the player has to navigate a map to find the key, warp to the final door and defeat Druaga.

I would complain that this whole game is way too hard for anyone to handle, but the awesome music and the beautiful cartoon graphics make everything far more soothing and bearable. I mean, Namco even added Taizo Hori, the original character from Dig Dug. That should give everyone a sense of the scope of this massive Mr. Driller collection and the content available.

There's also a story to this game, if anyone beats every single game variation. I recommend playing through all the game types before trying to take on the ordinary World Tour or Star Driller. To be honest, these variations are the best parts of the collection.
8.5/10
