So the game is easy to pick, not that long, and full the whole way. I adore that. Also the different levels are different enough to feel like you're really exploring a new place when doing multiple gameplays.
My only problem is that the game is really easy, even in hard mode. But that isn't much of a problem. I would have appreciated if the key served more use than "just another way to win" because I've been to the end 4 times, and I was pretty let down by finding that this item I've kept on me through all of the 3 precedent playthrought was just an equivalent of the orbs for one of the road.
Outside of that, excellent, just plain fun, I'll recommend it to some people.
