In the "Missing Game" I learned a lot about internet safety. I learned not to ever talk to people you don't actually know. You shouldn't go into open chats anyway.
Fantasma got Zack to go with him by pretending he's some kind of person Zack would like. He told Zack how amazing life would be with him, and he believed him. I mean .. who wouldn't ?
The detective work in this game is hard, yet kinda fun. You have to solve a lot of tough puzzles to try and rescue Zack.
This game gave me a pretty good idea of how to solve a case. However, I bet detectives and police put A LOT more work into it.
Though some students think it is fun I would suggest you not to do it anymore. It is kind of boring .. sorry !
