It was fun.... While it lasted....
1) Very catchy story.
2) Good graphics.
3) Innovating gameplay.
4) Very good looking characters.
CONS:
1) Very, very short play time (about 5 or 6 hours).
2) If you are gonna sell it back, it does not pay back.
3) Puzzles easily conquered.
4) Since the game is so short, you don't want to play it back, also because you still remember how to solve the puzzles.
So my advice is, if you want to spend some money (around $20 brand new) and you have some free time, go for it. But you have to have in mind that this game is very short and it won't give you the change to play it back. And if you bought it already, you won't get a good price for it. Better give it as a gift to one of your little brothers or sisters.
