This game isn't really all that good. The premise seems kind of interesting, but that's about it - there are games with relatively similar gameplay out there and they're BETTER.
Take the speed round - as many have commented, the timer starts long before you even gain control of the character. Saving all graydians AND beating the time limit is pretty much impossible. And even in non-speed levels the controls feel clunky and slow.
Perhaps the makers should have put less time into visual design (which is pretty good, though I'd imagine that player's mileage may vary on this) and more into making the game run faster.
