There's actually more Youtubers and Streamers who are focused on the game than reviewers it seems, so those are most of the reviews that seem that came first. Some people have had the game for several days, for example. I'll update with the site reviews as they come in.

Before you get to worried about it being another Kickstarter half-promise, know that this was delayed for good reason. I'm amazed at how polished it is, especially compared to some of its competitors. The art is beautiful, it has near-full (above competent) voice acting, and working features like instant keyboard or gamepad hot-swapping -- its biggest sin is that I couldn't latch onto a ladder a few times. That's really it in my 10-ish hour quest and 15-ish hour attempt to find everything. Some parts feel a little rushed and somewhat barren, absolutely, but I wouldn't go so far as to say "unfinished."
The selfless girl of A Hat in Time is not only a great role model, but she forges her own identity as a true mascot, with subtle notes of likable heroes like Dr. Who (complete with her own time-manipulating Tardis). Any game that makes me smile while I'm glued to it is a great one.
Gamespot - 7/10
For me it all comes together in the alps, a series of distant mountain peaks, each one vertiginous and tricksy, each one with its own gimmicks and secrets and treasures. After hours of moving between strange episodes, I was suddenly in free-range mode. I spent a fantastic afternoon in this huge, colourful space, working out where I wanted to get to, muddling through the process of getting there, grinding the most out of my move-set - a double-jump, an air-dash, a sort of targeted bottom-bounce and the ability to whack people with a brolly - and taking in the sights. Mafia Town, entertaining as it is, feels like a very distant memory up here.
I have no idea if this is how games like A Hat in Time get made - in stages, with later levels sometimes learning the lessons of the earlier levels. I am probably very wrong. But there is a palpable sense of discovery to the game, nonetheless, a sense of a design team unlocking the confidence to try the kinds of things the game increasingly tries to do. Whatever's really at work, A Hat in Time starts as a warm curio, and by its conclusion it is hitting some surprisingly high notes.

A Hat in Time is slow to start, but it's brimming with the charm and collectible-finding joy of classic 3D platformers. Collectibles are both fun to find and help guide you to the game's best secrets, and seeing everything there is to see is its own reward. The platforming isn't particularly challenging, nor does it do anything especially new, but A Hat in Time's cleverly themed worlds and witty quips lend it a more contemporary feel that's just right for satisfying a 3D platforming craving.
Metro - 8/10
This is a game with undeniable soul and an incredible amount of shine considering its budget. Thereís very little that A Hat in Time canít do as a classic platformer, and it really throws itself into creating a cute and cohesive universe for you to explore. The replayability of the title is great, and youíll get a lot of mileage revisiting older levels and finding hidden areas as you knit yourself a veritable treasure trove of superpowered hats over time. Sure, the developer's nostalgia for the genre seems to have encouraged it to include the flaws of those golden years of 3D platformers, but I weathered those blips with a smile, and you probably will too.
Will update with more as they come, but expecting a spread out process since this game has been under the radar for many.
By that point Super Mario Odyssey might already be out, and while weíre sure thatíll end up being the best 3D platformer of the year this will run it a surprisingly close second. A Hat In Time In Short: A hugely entertaining 3D platformer that channels the imagination and unpredictability of older games without becoming a prisoner to the past.
