It's an adventure/puzzle game on ps2, released in the early 2000.The remarkable part about this game was a very unique feature - as the protagonist Ico (the boy) you have to drag Yorda (the white girl) along you by keep holding the R1-button. When you left her alone for too long some dark creatures would appear and kidnap her, which would lead to a game over.It creates a very intense connection between the player and this character, which is why I just love this game! <3Hope you will have the opportunity to play it as well some day. It's worth it!
