This game was very good, but could be pretty violent, dark, and scary at times. Some of the enmities and many of the bosses were the cause of that. For example, I really thought that the bosses Fyrus and Morpheel were pretty scary. There are a few others besides them.
There were also a few parts that were kind of inappropriate. Like, there was one character, named Telma, who had a pretty low-cut shirt. She only appears a few times in the game, though. There's also the fairies, who don't have any clothes at all, although I've read that their hair covers what shouldn't be seen. I avoided going to them- (since you don't have to to beat the game)- by reading where they are located. If you want to avoid them as well, they are in Gerudo Desert in a hole near where you move the piece of the bridge back to the Bridge Elden or somewhere close to there.
Then there's the Poes. There's a side quest for them, but you don't have to complete it. You can defeat Poes by going into Wolf Mode, attacking them until they fall to the ground, then take their soul. I found this to be VERY DARK. I know this is just a game, but I still feel this to one of the darkest things in Twilight Princess. Anyway, there are a few times when you have to kill Poes to a few to progress through the game. I HATED doing those parts. I think it's only 5 or 6. There are a few where it seems that you have to do it, like this one in Snowpeak Ruins. But, you don't have to! It may take a couple tries, but you CAN avoid killing them if you keep trying!
Other than these things, I loved this game. The story and the good characters were amazing! Although, I wouldn't recommend this game for anyone under 12. I hope this review helps.
