I shouldn't review this.
In all fairness, I shouldn't review this because I honestly just don't like these kinds of games. That said, I will vote on, and review, this one.
The first thing I noticed upon starting the game is that both the music and the art are absolutely gorgeous. That said, the music's loop 'is' a bit short, so you'll be listening to the same thing restarting itself pretty much constantly. Fortunately, as stated before, it's 'great' music, so it's not really a bother.
The presentation was another bit of excellence. The game presents itself as something of a storybook, with each 'stage' being another page in the story.
It's impossible, so far as I can tell, to actually 'lose' the game. If you run out of time, you're simply sent to a humorous 'alternate' outcome at which point you simply spot the single difference to return to where you were.
So what more can I say, except this is very much the definition of a 'casual' game? You won't find a blistering button masher here, and while you 'can' challenge yourself by turning off the hints, the fact that you cannot lose means you could easily sit there looking for what you missed for an hour or more.
Even if you're like me, and really don't much like 'casual' games of this sort aren't your thing, I'd suggest you check this one out. The art alone makes it worth looking through.
