This works fine on my Windows 7 laptop. I haven't tried it on any other PCs, although I suspect the graphics would prove too much for older computers.
The graphics are nice (cartoony, but that's not necessarily a bad thing) and the game runs smoothly with no graphical glitches that I could find.
Red moves pretty fast. Given the amount of traveling you have to do in order to finish this game, this is a good thing.
Controls are pretty simple.
Red occasionally comes up with snatches of children's songs as she skips along, which is a nice touch. There are enough there to stop it getting repetitive, but it would have been nice if she'd recited the whole thing as opposed to one or two snatches.
The treasure chests hidden around the world are a good idea.
The minimap shows you where the next person you need to talk to is, which is a big help.
Camera angle and control are both very good. To be honest I can't remember if the controls are good or if the designers got it pretty much spot on without the need for controls, but either way I had absolutely no problems seeing where I was going ;)
The mazes. There's very little instruction as to what you're looking for or how many you have to find (it's all very well saying 'get all the flowers', but it's not much help). While you only have to go through each maze once, the design is so irritating - not difficult or frustrating, just irritating - that one would have been more than enough.
The traders. A nice idea, but if you spend your hard-earned cash on a bracelet or necklace or a pair of earrings, Red's character design means you'll never actually see her wearing them. Also, the game you have to play with the traders gets a little wearing. The first time was fun, but as with the mazes, once would have been enough.
It's quite hard finding your way around. The minimap doesn't come with any nice signs, so you're restricted to the signs in the game world, and there aren't quite enough of these.
AND THE JUST PLAIN MISC:
I'm not keen with what happens to the wolf in the end (though I guess it beats what happens in the story) but that's a personal thing, not a problem with the game design.
You have a cat. People are right when they say you can choose the design; you get to pick one of four cute little moggies to follow you around. However, following you around is all it does; you can't really interact with it to any great extent, it doesn't help in any way. Quite why this cat was included is a mystery to me.
It would have been nice if you could have gone inside some of the houses.
Still, it's a sweet, fun little game (and for concerned parents, completely free of blood, guts, violence and profanity, although very young children may easily get bored) and the size of both game maps will keep you busy for a while.
