The game is full of puzzles: picture puzzles, crosswords and a 13 level maze game which features mini puzzles of various difficulty, all presented to you by 3 different characters who encourage but at the same time berate you!! At the end of each game, they will also assess your performance and give you a rating.
You can choose different difficulty levels too, which is great. The furthest I have reached is level 7 of the main game, and I would be confident that, as this is version 1.02, that this is a full game albeit unreleased.
