Excellent, Except For One Thing
The effort that was put into this submission shows. Everything from the graphics, music, sound effects, and voice acting is of very high caliber. The problem solving platform levels are just perfect for an educational game, and the lessons about online safety are very serious and relevant. Overall a very high quality game.
However, I do have one major criticism about the game, and that is the need to avoid stereotyping. Real "strangers" don't have evil laughs and pointed teeth. It may sound trivial, but remember that this is intended to educate children, and that the real challenge for children is when a "friend" - someone nice they met in a chat room - asks them to do something that they shouldn't. Real strangers use nicety and politeness to break the mold of being the "bad guy", and children need to be taught this.
Besides this complaint, this submission ranks first class all the way. Good job!
