The game doesn't even matter. How awesome is the title Captain Toad: Treasure Tracker? How awesome is the idea of a Toad character finally getting their game and it's all about exploration, adventure and tracking down treasure? There's no possible way for this game to be terrible with a title and premise like that. Do I think Captain Toad: Treasure Tracker will be succesful? Well, that's another matter entirely, but it certainly has potential.
Let me just preface that before I even started playing Captain Toad, before I knew it would be available to play on the show floor, I'd noted that I was reserved about the game. 3D games where the camera actively become not just the eyes of the player, but take on the role of becoming part of the puzzle, part of the challenge themselves typically suffer for it. Cameras are generally a frustrating part of playing thirs-person games already, but actively depriving the player of information for the sake of creating "puzzles" is like saying tank controls in survival horror games adds to the tension. You're not wrong, but you're not right for the reasons you're stating either.
Of course, as soon as I actually did start playing the game I found my initial worries on-target. For those unfamiliar, Captain Toad: Treasure Tracker is a third-person game where the camer floats around a 3D island of sorts, they then rotate the camera around this island so they can guide Captain Toad through a series of traps and obstacles to fine coins and "Diamonds". These items are often hidden down secret staircases, in odd corners, or down surprise tunnels which require a very specific camera angle while Toad is in a very specific location to discover.
The very first level puts Toad right next to a bridge that leads straight to the finish line, where when Toad begins to cross the bridge crumbles and drops him into a crevice below. Boom, Captain Toad's very first lesson is in camera controls, because Toad is immediately placed into an area the player doesn't expect him to be and says, "Find him." The rest of the level is then dedicated to encouraging the player to twist and turn the camera in an attempt to open people up to the idea of constantly looking for secrets.
After helping to establish the role of the camera in the game, the further levels focused on fleshing out the core gameplay like maintaining control of Toad while shifting the camera around. Then a step after that there's introducing non-core mechanics that add depth to the experience. Basically, it's a Nintendo game; it's not rocket science.
All in all, the game isn't difficult enough to get up in arms over despite its focus on camera-as-a-puzzle gameplay. Each level is easy enough that even the rather consistent mistakes I'd make due to the camera weren't frustrating enough to give me pause. Still, being cornered into mistakes just because of the camera angle seems like a poor gameplay mechanic to me. Luckily one of Nintendo's greatest strengths is intuitive and enjoyable level design, so I don't doubt Nintendo will keep the frustrations to a minimum.
I do have one last question bouncing around in my head after playing Captain Toad at E3. That's whether this game grew out of the mini-game in Super Mario 3D World, or if this game was planned all along and the mini-game was meant to introduce us to the concept. I suppose it doesn't really matter one way or another, but it does give detail to my feeling that Captain Toad: Treasure Tracker doesn't feel like a full game, as opposed to a fun selection of mini-games.
Ah, it appears I've spent most of my time here noting my worries and complaints, which do stand at the forefront of my thoughts about Captain Toad: Treasure Tracker. Still, I did enjoy the game. It's built on the Super Mario 3D World engine and looks outstanding, it's very intuitive to play and the puzzles can be quite charming. You know, it's a Nintendo game.
Captain Toad: Treasure Tracker is a Wii U exclusive planned to be released holiday of 2014.
