Fantastic, simple, perfect, addicting, amazing, immersive, if you need a game with those qualities, try this one
You start knowing nothing, it may sound weird but it's the spice to keep playing and revealing your memories and your own life about that place. The storyline its soo deep and so incredible that you'd even cry when it's finally over.
Like all great games, it has different endings, the good ending, the almost good ending, and the bad ending, not to mention, the perfect ending, which needs to unlock the secret place completing a series of behaviors like choosing to do not pick up an item at a time and catching it later.
The characters are all charismatic, and you'll feel as they're really your friends and as friends, you are going to protect them at all costs.
The game is really worth playing, the sound, even poor in quality, follows the maps, the graphics are great for a side scrolling game, and the story, perfect.
